74HC126PW,118

Overview

The Nexperia 74HC126PW,118 is a quad buffer and line driver featuring three-state outputs controlled by active HIGH output enable inputs. It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes the TSSOP14 (SOT402-1) package with 14 leads. The device provides non-inverting logic buffering with high noise immunity and low power dissipation characteristics compliant with JEDEC standards.

Feature Summary

• Quad buffer/line driver with three-state outputs
• Active HIGH output enable control
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation

Applications

• Signal buffering in mixed-voltage environments
• Line driving for data transmission interfaces
• Bus-oriented communication systems requiring tri-state isolation

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's current datasheet to confirm the exact package variant and temperature rating. Ensure that the procurement documentation matches the required JEDEC compliance levels and ESD protection specifications defined in the official product data sheet.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required for bus applications. The wide supply voltage range supports various logic families. Verify that the TSSOP14 package dimensions align with the PCB footprint requirements and that the operating temperature range meets the environmental constraints of the target application.

Part Context

This part belongs to the 74HC series of high-speed silicon-gate CMOS logic devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) standards. The 74HC126 family is functionally similar to the 74HC125 but utilizes active HIGH output enables instead of active LOW enables.

Replacement Considerations

The 74HCT126PW,118 serves as a direct functional replacement within the same package, differing primarily in input voltage threshold compatibility with TTL levels rather than CMOS levels.
