MC74HC157ADG

Signal Switches, Multiplexers, Decoders Overview

The MC74HC157ADG is a quad 2-input data selector manufactured by onsemi, belonging to the HC logic series. It features four independent multiplexers in a single package, routing either input group A or B to the Y outputs based on the select line. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a TSSOP-16 package. It functions with non-inverted outputs and includes an active-low output enable feature that forces outputs low when asserted.
