74HC1G125GW,125

Overview

The Nexperia 74HC1G125GW,125 is a single-channel 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. Input leakage current is limited to 1.0 μA maximum, while the supply current reaches 20 μA maximum.

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 rail using current-limiting resistors.
• Delivers symmetrical output impedance and balanced propagation delays for consistent signal timing.
• Includes ESD protection compliant with JEDEC standards, exceeding 2000 V for Human Body Model and 1000 V for Charged Device Model.

Applications

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

Procurement Notes

Verify the specific ordering suffix '125' corresponds to the TSSOP5 (SOT353-1) package variant when sourcing. Confirm that the component meets RoHS compliance requirements as specified in the product documentation. Ensure the procurement channel provides original manufacturer packaging to maintain integrity during surface-mount assembly processes.

Selection Notes

Select this component for applications requiring a single-channel buffer with high noise immunity and wide supply voltage flexibility. The HC logic family ensures compatibility with standard CMOS levels across the 2.0 V to 6.0 V operating range. Consider the TSSOP5 package dimensions for space-constrained PCB layouts where minimal footprint is required.

Part Context

This component belongs to the Nexperia 74HC1G series of single-gate logic devices. It is part of a broader family including inverters, NAND gates, and NOR gates, all sharing similar compact packaging and performance characteristics. The 74HC designation indicates High-speed CMOS technology, distinguishing it from the 74HCT series which targets TTL-compatible input levels.

Replacement Considerations

The 74HC1G125GV,125 serves as a functional equivalent utilizing the SC-74A (SOT753) package instead of the TSSOP5 form factor. Both variants share identical electrical specifications and pin configurations, allowing for potential substitution if package availability dictates.
