74HC125PW,112

Overview

The 74HC125PW,112 is a quad buffer and line driver manufactured by Nexperia (formerly NXP) in a TSSOP14 package. It features four independent 1-bit drivers with true outputs controlled by active-low output enable inputs (nOE). The device operates on a supply voltage range of 2.0 V to 6.0 V. It complies with JEDEC standards JESD8C and JESD7A. Inputs include clamp diodes for interfacing with voltages exceeding VCC. The component supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Quad buffer/line driver with three-state outputs controlled by active-low nOE inputs
• Wide supply voltage operation from 2.0 V to 6.0 V compliant with JEDEC standards
• High noise immunity and low power CMOS dissipation
• Robust ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Bus-oriented transmissions
• Clock driving
• Buffering memory and address buses

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this part when a quad bus driver with three-state control is required. Ensure the design accommodates the TSSOP14 thermal characteristics, as total power dissipation derates linearly above 81 °C. Confirm that the application voltage falls within the 2.0 V to 6.0 V range and that input signals respect the clamping current limits if they exceed VCC.

Part Context

This component belongs to the 74HC/HCT125 family of logic integrated circuits. It is functionally identical to the 74HCT125 but utilizes CMOS input levels rather than TTL levels. The PW suffix indicates the Thin Shrink Small Outline Package (TSSOP), distinguishing it from the standard SO package variant.

Replacement Considerations

The 74HC125D serves as a direct pin-compatible replacement using the SO14 package. Other compatible variants include the 74HC125DB (SSOP14) and automotive-qualified versions such as the 74HC125PW-Q100, provided the temperature and reliability requirements are met.
