SN74AS153NS

Overview

The SN74AS153NS is a dual 4-input multiplexer from the Texas Instruments AS-TTL logic series. It features two independent multiplexing circuits, each selecting one of four data inputs based on address lines. The device operates within a supply voltage range of 4.5V to 5.5V and supports through-hole installation in a 16-pin DIP package. It is rated for commercial temperature operation between 0°C and 70°C.
