Summary of NL17SZ125DFT2G Series Products

The NL17SZ125DFT2G from onsemi is a single non-inverting buffer featuring 3-state outputs. This device is engineered for logic-level applications where signal buffering, isolation, and output control are required. Housed in compact packages such as SC-88A (SC-70-5/SOT-353), SOT-553, SC-74A, SOT-953, and UDFN6, it is particularly suitable for high-density board designs. The buffer supports digital circuit architectures across a wide supply voltage (1.65 V to 5.5 V), making it versatile for a range of voltage domains in modern electronics.

Main Attributes of NL17SZ125DFT2G

A primary highlight of the NL17SZ125DFT2G is its broad V_CC operating range from 1.65 V to 5.5 V, facilitating integration into both low-voltage and legacy systems. The device delivers a fast propagation delay (typical t_PD of 2.3 ns at V_CC = 5 V), suited for high-speed logic signal transmission without compromising data integrity. Inputs and outputs tolerate voltages up to 5.5 V, supporting flexible interfacing and robust design against overvoltage events.

The buffer’s 3-state output allows for precise control in shared bus configurations, minimizing contention. Partial power-down protection (I_OFF feature) is included, supporting fault-tolerant designs. With the capability to source or sink 24 mA at 3 V, NL17SZ125DFT2G enables driving moderate loads. Its low chip complexity (<100 FETs) makes it efficient for resource-constrained logic circuits. Notably, the device is available as AEC-Q100 qualified and PPAP capable for automotive and stringent industrial applications. All variants are Pb-Free, halogen Free/BFR-Free, and compliant with RoHS requirements.

Absolute Limits and Reliability Aspects of NL17SZ125DFT2G

To ensure system integrity, it is essential that the NL17SZ125DFT2G operates within its maximum ratings. Exceeding specified limits can permanently damage the device and compromise reliability. ESD performance is robust, tested to both ANSI/ESDA/JEDEC JS-001-2017 for HBM and EIA/JESD22-C101-F for CDM standards. Stresses exceeding specified levels, including voltage, current, or temperature outside design criteria, may lead to functional failures or lifetime reduction. For long-term durability, designers should strictly observe recommended maximum values as listed in the manufacturer’s datasheet.

Suggested Usage Parameters for NL17SZ125DFT2G

Reliable operation of the NL17SZ125DFT2G is assured within the recommended conditions defined by onsemi. Functional specifications apply for supply voltages between 1.65 V and 5.5 V. Operational stability over temperature and humidity should also be maintained within the ranges advised in the technical documentation. Exceeding the recommended parameters can result in unpredictable behavior or early device wear. For mission-critical designs, careful attention to these operating windows maximizes system uptime and buffer responsiveness.
