Introduction to the SN74AUC1G08YZAR by Texas Instruments

The SN74AUC1G08YZAR, manufactured by Texas Instruments, is a single-channel, 2-input positive-AND gate integrated circuit presented in a compact 5-ball DSBGA package (measuring just 1.4 x 0.9 mm). It is part of the SN74AUC1G08 series, which utilizes NanoStar™ and NanoFree™ package technologies—breakthroughs in IC miniaturization aimed at enabling designs where PCB area and device height are at a premium. Widely adopted in cutting-edge applications ranging from portable consumer electronics to mixed-voltage industrial systems, the SN74AUC1G08YZAR supports reliable logic-level translation, robust ESD protection, and remarkably low power consumption.

Main Attributes and Functional Overview of SN74AUC1G08YZAR

The design of the SN74AUC1G08YZAR centers on flexibility and power efficiency for next-generation logic circuits:

Ultra-Low Operating Voltage: The device operates across a wide supply voltage range (0.8 V to 2.7 V), but is optimized for a typical core voltage of 1.65 V to 1.95 V. Mixed-signal platforms benefit from 3.6 V I/O tolerance, enabling seamless interconnection across varying logic domains.

Functionality: Realizing the Boolean function Y = A ∙ B in positive logic, this IC provides a single 2-input AND gate per package, supporting fundamental logic requirements in space-limited designs.

Power Management: Integrated I_off circuitry disables outputs during partial power-down states, preventing backflow current and enabling safe operation under power sequencing or dynamic supply conditions.

Output Drive: Capable of ±8 mA output drive at 1.8 V, it is suitable for direct connection to moderate loads.

ESD and Latch-Up Protection: Robust against electrostatic discharge, the device exceeds the JESD 22 standards with ratings of 2000 V (Human Body Model), 200 V (Machine Model), and 1000 V (Charged Device Model). Latch-up immunity exceeds 100 mA as per JESD 78 Class II.

Low Static Power: Maximum quiescent current (I_CC) is rated at just 10 μA, supporting ultra-low-power standby and battery-operated applications.

Electrical Parameters and Performance Data of SN74AUC1G08YZAR

Engineered for high-performance, low-voltage operation, the SN74AUC1G08YZAR exhibits:
