SN74AHCT1G125DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHCT1G125DCKR is a single bus buffer gate and line driver featuring three-state outputs, manufactured by UMW. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides an output drive capability of ±8 mA at 5 V and maintains a maximum quiescent supply current (ICC) of 10 µA. Propagation delay (tpd) is specified as a maximum of 10 ns at 5 V with a 15 pF load. Inputs are TTL-voltage compatible, accepting high-level input voltages (VIH) of 2 V and low-level input voltages (VIL) of 0.8 V. The component is housed in the SC-70-5 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number may correspond to multiple physical packages such as SOT-23-5 or DFN6. Confirm the manufacturer designation aligns with UMT specifications rather than other vendors using similar part numbers. Ensure the datasheet version corresponds to the delivered batch for accurate electrical parameter validation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with three-state functionality is required for 5 V logic systems. The AHCT series ensures compatibility with TTL input levels while maintaining CMOS performance characteristics. Consider the SC-70-5 package constraints regarding thermal dissipation and board space. Verify that the operating temperature range meets the environmental requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AHCT1G125 family of single bus buffers. It shares functional similarities with other single-gate logic ICs but is distinguished by its specific AHCT technology and three-state output configuration. The DCKR suffix indicates the SC-70-5 surface-mount package variant supplied in tape and reel format for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the SN74AHCT1G125DCK from Texas Instruments and the 74AHCT1G125GW from Nexperia. These alternatives offer identical logical functions and pinouts but may differ in specific electrical parameters or package dimensions. Verify cross-manufacturer datasheets for propagation delay and drive strength equivalence before implementation.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the three-state output controlled?

The output is disabled when the output-enable (OE_) input is high. When OE_ is low, data passes from the A input to the Y output.

What is the maximum propagation delay?

The maximum propagation delay (tpd) is 10 ns at 5 V with a 15 pF load.
