74HC125PW,112

Overview

The Nexperia 74HC125PW,112 is a quad buffer and line driver featuring three-state outputs controlled by active LOW enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standards JESD8C and JESD7A. The device utilizes CMOS technology for low power dissipation and high noise immunity. It includes input clamp diodes to support interfacing with voltages exceeding VCC. The component is specified for operation across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Quad buffer/line driver configuration with independent three-state outputs
• Wide supply voltage compatibility from 2.0 V to 6.0 V
• Input clamp diodes allow interface to voltages higher than VCC
• High ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Bus-oriented communications systems
• Clock drivers requiring three-state control
• Memory and signal switching applications

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 package variant SOT402-1 as defined in the official datasheet. Confirm that the procurement channel sources the product directly from Nexperia or authorized distributors to ensure authenticity. Check current production status and longevity program details before finalizing orders.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required. Ensure the system logic levels match the CMOS specifications of the HC series. Verify that the operating voltage remains within the 2.0 V to 6.0 V range. Consider the TSSOP14 package dimensions if space constraints are a factor in the PCB layout design.

Part Context

This part belongs to the 74HC/HCT family of high-speed Si-gate CMOS logic devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) standards. The device serves as a standard solution for buffering digital signals in mixed-voltage environments while providing isolation through its high-impedance output states.

Replacement Considerations

The 74HCT125PW,112 is a compatible alternative offering TTL-level input compatibility instead of CMOS levels. Both variants share identical pinouts and functional descriptions but differ in input threshold voltage requirements.
