SN74ALS137AD

Signal Switches, Multiplexers, Decoders Overview

The SN74ALS137AD is a 3-line to 8-line decoder/demultiplexer with latches on the three address inputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to 70°C. The device features two output enables (G1 and G2) that control outputs independently of select or latch-enable inputs. Propagation delay times from address inputs A, B, C to outputs Y are specified between 5 ns and 20 ns depending on logic state transitions.
