74AHCT1G125DBVTG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHCT1G125DBVTG4 is a single-channel, non-inverting buffer and line driver from the Texas Instruments 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs for bus-oriented applications. The device utilizes CMOS technology with TTL-compatible inputs, ensuring reliable interfacing with standard logic systems. Packaged in a compact SOT-23-5 surface-mount configuration, it supports operation across an extended industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• TTL-compatible input thresholds enable direct interface with standard TTL logic devices without additional level shifting components.
• Three-state output architecture allows multiple drivers to share a common data bus while preventing signal contention.
• Single-channel design provides a dedicated buffering path for high-speed signal integrity in space-constrained layouts.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock distribution and buffering circuits
• Data bus transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TG4' indicates RoHS compliance and green manufacturing status as per Texas Instruments standards. Confirm the package designation matches the required SOT-23-5 footprint for PCB layout compatibility. Ensure the operating voltage requirements align strictly with the 4.5V to 5.5V specification to prevent functional degradation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level input compatibility is required alongside low-power CMOS performance. The three-state feature is essential for multiplexed bus systems where signal isolation is necessary. Consider the SOT-23-5 package size for applications with strict spatial limitations compared to larger DIP or SOIC packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AHCT1Gxx series of single-gate logic ICs. It shares the same logical function as the SN74AHC1G125 but differs in input threshold characteristics to support TTL signaling. The DBVT package variant offers a small outline transistor package suitable for automated surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AHC1G125DBVTG4: Similar function but requires 2V to 5.5V supply; inputs are not TTL-compatible. SN74AHCT1G125DCKT: Same electrical function but housed in SC-70-5 package instead of SOT-23-5.
