74AHCT125D,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT125D,112 is a quad buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the AHCT logic series for TTL-compatible input levels. The device provides four independent channels in a 14-pin SO package (SOT108). Key electrical specifications include a maximum propagation delay of 7.5 ns at 4.5 V to 5.5 V, an output current capability of ±8 mA, and a maximum static supply current of 40 µA. It supports surface mount installation and functions reliably across an industrial temperature range from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four non-inverting buffer/line drivers with three-state outputs controlled by active-low enable inputs.
• Features TTL-compatible input levels suitable for interfacing with standard digital logic systems.
• Includes Schmitt-trigger action on all inputs to ensure tolerance for slower rise and fall times.

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus buffering and isolation in multi-device communication systems.
• Line driving for high-speed signal transmission in industrial control environments.
• Voltage level translation between TTL and CMOS logic domains.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized Nexperia distributors or certified suppliers.
