74HCT157D,652

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HCT157D,652 is a quad 2-input multiplexer integrated circuit belonging to the HCT logic family. It features four independent 2-to-1 data selectors housed in a 16-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides non-inverted outputs with a maximum propagation delay of 30 ns at 4.5 V and 50 pF load. The component supports single-ended inputs and includes an active-low strobe input for enabling or disabling the selected data channels.
