Broadcom Limited HCPL-0211#500

Product Summary HCPL-0211#500 Logic Gate Optocoupler by Broadcom Limited

The HCPL-0211#500 from Broadcom Limited is an advanced optoisolator device designed for logic level isolation and signal transfer in demanding electronic systems. It offers a robust push-pull, totem pole output structure within a tall 8-pin SOIC package. Capable of supporting a signal rate of 5 Mbps and providing an insulation voltage rating of 3750 Vrms, the HCPL-0211#500 is a member of Broadcom’s very high common-mode rejection (CMR) optocoupler series, ideal for digital communications, microprocessor interfaces, and ground loop elimination. At its core, the HCPL-0211#500 supports secure system isolation while ensuring high-speed logic compatibility.

Main Technical Specifications and Performance of the HCPL-0211#500

The HCPL-0211#500 is distinguished by its technical attributes tailored for integration into high-performance isolation circuits. Its minimum CMR of 10 kV/µs at a common mode voltage of 1000V ensures high reliability, even in environments with extreme electrical noise or rapid transients. The device supports a wide supply voltage range from 4.5V to 20V, enabling seamless compatibility with TTL, LSTTL, and CMOS logic systems. The optocoupler’s GaAsP LED and Schmitt-triggered receiver stage provide digital waveforms without the need for additional signal conditioning, simplifying overall circuit design. Guaranteed propagation delays of up to 300 ns across the -40°C to +85°C temperature spectrum allow for effective timing control in digital communications, with a typical delay as low as 150 ns under standard operating conditions.

Electrical Properties and Operating Parameters of the HCPL-0211#500

Engineers selecting the HCPL-0211#500 optoisolator benefit from well-defined electrical parameters. Input LED drive currents of 1.6 mA (recommended operational guardband up to 2.2 mA for longevity) enable low power consumption and robust switching. Output characteristics support direct logic interfacing, with totem pole outputs negating the need for pull-up resistors. The HCPL-0211#500 exhibits stability over a broad ambient temperature range, with propagation and switching delays tightly controlled from -40°C to +85°C. Key switching specifications—such as rise and fall times and common mode transient immunity—are directly attributable to its advanced shielding and internal architecture. In practical design scenarios, using a 0.1-µF bypass capacitor between pins 5 and 8 is required for optimal high-frequency performance and noise suppression.

Available Packages and Physical Dimensions of the HCPL-0211#500

The HCPL-0211#500 is available in an SOIC-8 tall package, designed for ease of assembly and integration into densely packed electronic systems. The standardized footprint of 8-pin packages provides flexible PCB layout options and supports both DIP and surface-mount variants across the series. Engineers should note details such as maximum floating lead protrusion and lead coplanarity, which are critical for automated assembly and soldering reliability, especially when considering JEDEC-compliant reflow profiles. In addition, rugged mechanical design ensures durability during production and field deployment.

Functional Guidelines and Suggested Application Circuits for the HCPL-0211#500

For system designers, the HCPL-0211#500 facilitates the isolation of high-speed logic signals in applications ranging from computer-peripheral and microprocessor interfaces, to pulse transformer replacements and high-speed line receivers. The Schmitt-trigger input and totem pole output eliminate unwanted oscillations and ensure rapid signal transitions. Example circuits include LSTTL to LSTTL interfaces, and LSTTL-to-CMOS level translation, where a propagation delay ceiling of 300 ns is easily accommodated. Strategies for driving the LED, including series and parallel configurations for current control, are well-supported by the device’s low input threshold and fast response characteristics. Engineers should ensure that ESD precautions are exercised during handling to avert degradation, and that input drive currents provide sufficient guardband for long-term LED performance.

Regulatory Compliance and Safety Features of the HCPL-0211#500

Safety is a key consideration for isolated interfaces, especially in industrial and medical equipment. The HCPL-0211#500 is UL recognized under UL1577 (3750 Vrms for 1 minute) and is CSA approved, ensuring adherence to international standards for electrical isolation. While not designed for automotive, military, or aerospace use, its credentials under IEC/EN/DIN EN 60747-5-5 for related models provide confidence in regulatory environments requiring verified insulation characteristics. Designers should reference safety limit data and maintain protective circuits as prescribed to preserve isolation integrity.

Alternative or Substitute Models Comparable to HCPL-0211#500

In cases where the HCPL-0211#500 is unavailable or specific packaging, performance, or feature sets are required, Broadcom’s portfolio includes several alternative optoisolator models. The HCPL-2211, HCPL-2212, HCPL-2232, and HCNW2211, among others, feature similarly high CMR and compatible logic gate output configurations, with variations in insulation voltage, LED type, and package format. For wider isolation voltage ratings, the HCNW2201 and HCNW2211 provide up to 5000 Vrms. Selection engineers should cross-reference these series for matching propagation delays, output enable/disable options, and package preferences according to system requirements.
