74HC125PW,118

Overview

The Nexperia 74HC125PW,118 is a quad buffer and line driver featuring four non-inverting buffers with three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes a TSSOP14 package (SOT402-1). The device includes input clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standards JESD8C and JESD7A, ensuring high noise immunity and low power dissipation.

Feature Summary

• Quad buffer/line driver with three-state outputs controlled by active LOW enable inputs
• Wide supply voltage range from 2.0 V to 6.0 V supporting CMOS logic levels
• Input clamp diodes allow interface to voltages in excess of VCC using current limiting resistors
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Signal buffering in digital communication systems
• Line driving for data transmission interfaces
• Voltage level translation between different logic families
• Bus holding and signal isolation in microcontroller circuits

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for absolute maximum ratings to prevent permanent damage during operation or testing phases.

Selection Notes

Select this component when a quad buffer with three-state capability is required for CMOS applications. The wide supply voltage range supports various system architectures. Verify that the TSSOP14 package fits the PCB layout constraints and thermal requirements of the target application environment.

Part Context

This part belongs to the 74HC series of high-speed silicon-gate CMOS devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) logic families. The device is specified in compliance with JEDEC standard JESD7A, ensuring interoperability with standard digital logic components in mixed-voltage systems.

Replacement Considerations

Check for direct equivalents such as the 74HCT125PW,118 if TTL input levels are preferred. Other manufacturers may offer compatible parts under the same 74HC125 designation. Verify electrical characteristics and package dimensions before substitution.
