74HC1G126GW,125

Overview

The Nexperia 74HC1G126GW,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 utilizes CMOS technology for low power dissipation. The device provides symmetrical output impedance and high noise immunity. It includes input clamp diodes to allow interfacing with voltages exceeding VCC using current-limiting resistors. The component is housed in a TSSOP5 (SOT353-1) package with five leads.

Feature Summary

• Single-channel buffer/line driver with three-state output controlled by an OE pin
• Wide operating supply voltage range from 2.0 V to 6.0 V
• Input clamp diodes enable interface to voltages exceeding VCC
• CMOS construction ensures low power dissipation and high noise immunity

Applications

• Bus buffering applications requiring signal isolation
• Line driving in mixed-voltage environments
• Interface circuits utilizing current-limiting resistors for over-voltage inputs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status and ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity and traceability.

Selection Notes

Select this component when a single-channel buffer with three-state capability is required. Ensure the application voltage falls within the 2.0 V to 6.0 V range. Consider the TSSOP5 package constraints for PCB layout. Verify that the input signals do not exceed absolute maximum ratings without appropriate current limiting.

Part Context

This part belongs to the Nexperia 74HC1G series of single-gate logic devices. It is functionally related to the 74HCT1G126 but differs in input threshold levels, supporting CMOS rather than TTL input levels. Both variants share similar electrical characteristics and packaging options within the same product family.

Replacement Considerations

The 74HCT1G126GW,125 serves as a direct functional substitute within the same package, differing primarily in input threshold specifications.
