DM74S153N

Signal Switches, Multiplexers, Decoders Overview

The DM74S153N is a dual 1-of-4 line data selector/multiplexer manufactured by onsemi. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0 °C to +70 °C. The device features two independent four-line sections with common select inputs A and B, and separate strobe inputs for each section. Typical average propagation delay times are 6 ns from data, 9.5 ns from strobe, and 12 ns from select. Power dissipation is typically 225 mW.
