SN74HC125DT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125DT is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It belongs to the HC logic series and operates on a supply voltage range of 2 V to 6 V. The device features four non-inverting channels with Schmitt-trigger inputs for noise immunity. It provides high-level output current of -7.8 mA and low-level output current of 7.8 mA. The propagation delay is specified at 150 ns at 2 V, 30 ns at 4.5 V, and 25 ns at 6 V. It is housed in a 14-SOIC package and supports surface-mount installation.
