SN74AHCT1G126DBVT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHCT1G126DBVT is a single bus buffer gate with three-state output manufactured by Texas Instruments. It belongs to the AHCT logic series, ensuring compatibility with TTL-driven inputs while operating on CMOS technology. The device functions as a non-inverting buffer, passing data from input A to output Y when the output enable (OE) signal is low. When OE is high, the output enters a high-impedance state. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 8.5 ns at 50 pF load. The component provides ±8 mA output drive capability and is housed in a SC-74A or SOT-753 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'VT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the required moisture sensitivity level and RoHS compliance status. Cross-reference the full TI part number to distinguish between standard production variants and any potential military or enhanced reliability grades.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with TTL-compatible inputs is required in a compact surface-mount footprint. It is suitable for designs needing precise timing control with low propagation delay. Consider the 4.5 V to 5.5 V supply constraint; if lower voltage operation is needed, an AHC variant may be more appropriate. Verify that the 8 mA drive current meets the load requirements of the destination circuit.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is a member of the SN74AHCT1Gxx family of single-gate logic devices. It shares functional similarities with the SN74AHCT1G125 but differs in internal logic configuration. The AHCT series bridges the gap between older TTL standards and modern CMOS performance, offering robust switching speeds while maintaining backward compatibility with established system architectures.
