74LV125N,112

Overview

The 74LV125N,112 is a low-voltage Si-gate CMOS quad buffer and line driver featuring four non-inverting channels with 3-state outputs. It operates within a supply voltage range of 1.0 V to 5.5 V and is pin-compatible with 74HC125 and 74HCT125 devices. The component utilizes active LOW output enable inputs (nOE) to control high-impedance states. It supports TTL input levels between VCC = 2.7 V and VCC = 3.6 V and provides ESD protection exceeding 2000 V (HBM). The device is housed in a 14-lead DIP package and functions reliably across temperatures from -40 °C to +125 °C.

Procurement Notes

Verify the specific ordering suffix '112' against current manufacturer documentation to confirm package type and availability status. Confirm that the DIP14 package variant matches the design requirements for through-hole mounting. Check for any product change notices or end-of-life declarations that may affect long-term supply continuity.

Selection Notes

Select this component when a quad buffer with 3-state capability is required for low-voltage digital systems. Ensure the application voltage falls within the 1.0 V to 5.5 V range. Consider the propagation delay characteristics at the target operating voltage if timing constraints are critical. Verify thermal dissipation requirements based on the total power dissipation limits for the DIP14 package.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by NXP Semiconductors. The 74LV125 specifically serves as a quad buffer with 3-state outputs, offering compatibility with standard 74HC and 74HCT logic families while supporting lower supply voltages. It is designed for general-purpose digital signal processing and interface applications requiring high drive capability and noise immunity.

Replacement Considerations

Direct functional substitutes include the 74LV125D, 74LV125DB, and 74LV125PW variants, which share identical electrical specifications but differ in packaging formats such as SO14, SSOP14, and TSSOP14 respectively.
