74HC1G125GW,165

Overview

The Nexperia 74HC1G125GW,165 is a single bus buffer and line driver featuring a three-state output. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and high noise immunity. Propagation delay (A to Y) typically ranges from 8 ns at 6.0 V to 24 ns at 2.0 V. Enable time (OE to Y) typically spans 7 ns to 19 ns depending on the supply voltage.

Feature Summary

• Provides a single non-inverting buffer with three-state output capability controlled by an active LOW enable input.
• Features inputs equipped with clamp diodes to allow interfacing with voltages exceeding the supply voltage using current limiting resistors.
• Delivers symmetrical output impedance and balanced propagation delays for consistent signal timing.

Applications

• High-speed data transmission lines
• Clock distribution buffers
• Bus-oriented transmissions

Procurement Notes

Verify that the ordering suffix '165' corresponds to the specific tape and reel configuration required for your assembly process. Confirm package availability matches the SOT353-1 (TSSOP5) outline specified in the datasheet. Ensure compliance with RoHS directives and check for any recent product change notices affecting marking or material composition before finalizing orders.

Selection Notes

Select this component when a single-channel buffer with three-state control is required for HC logic families. It is suitable for applications needing wide supply voltage flexibility between 2.0 V and 6.0 V. Consider the 74HCT1G125 variant if TTL-level input compatibility is necessary instead of standard CMOS levels.

Part Context

This part belongs to the Nexperia 74HC/HCT1G series of single-gate logic devices designed for space-constrained surface-mount applications. The GW suffix indicates the TSSOP5 plastic thin shrink small outline package (SOT353-1). These components are engineered for general-purpose digital logic buffering in consumer electronics and industrial equipment operating across extended temperature ranges.

Replacement Considerations

The 74HCT1G125GW,125 serves as a functional substitute within the same family, offering identical pinout and logical operation but with TTL-compatible input levels rather than CMOS levels. Verify input voltage thresholds match the source driver specifications before substitution.
