74AHCT1G125W5-7

Overview

The 74AHCT1G125W5-7 is a single non-inverting buffer/bus driver with a 3-state output manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and provides an output drive capability of ±8 mA at 5.0V. The device features Schmitt trigger action at all inputs, ensuring tolerance for slower input rise and fall times. It is housed in a SOT25 package and supports an operating free-air temperature range from -40°C to 125°C.

Feature Summary

• Single non-inverting buffer with 3-state output functionality
• Schmitt trigger action at all inputs for noise immunity
• ESD protection exceeding 2000-V Human Body Model standards

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TV, DVD, DVR, and set-top boxes
• Phones, personal navigation/GPS devices, MP3 players, cameras, and video recorders

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the W5 suffix denotes the SOT25 package while SE denotes SOT353. Confirm RoHS compliance status and lead-free finish requirements against current manufacturing notices. Ensure the application environment remains within the specified 4.5V to 5.5V supply voltage range and the -40°C to 125°C operating temperature limits to maintain performance specifications.

Selection Notes

Select this component when a single-channel non-inverting buffer with high-impedance state control is required. The AHCT logic series ensures TTL-compatible input thresholds suitable for 5V systems. Consider the SOT25 package size for space-constrained surface-mount designs. Verify that the ±8 mA output drive current meets the load requirements of the destination circuitry.

Part Context

This part belongs to the 74AHCT1G series of single-function logic ICs produced by Diodes Incorporated. It is designed for low-power CMOS applications requiring robust signal buffering. The device integrates ESD protection mechanisms compliant with JESD 22 standards, enhancing reliability in consumer electronics environments.

Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 74AHCT1G125 function in a SOT25 package. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.

FAQ

How does the Output Enable (OE) pin affect the output state?

When a HIGH-level is applied to the OE pin, the output enters a high impedance state regardless of the input A level.

What is the maximum operating junction temperature?

The absolute maximum rating for the operating junction temperature is 150°C, though the recommended operating free-air temperature extends up to 125°C.
