DM74ALS151M

Signal Switches, Multiplexers, Decoders Overview

The DM74ALS151M is a 1-of-8 line data selector/multiplexer manufactured by onsemi. It features full on-chip decoding to select one of eight data sources based on a three-bit binary code at the Select inputs (C, B, A). The device provides two complementary outputs: Y (non-inverting) and W (inverting). A Strobe input disables all data inputs when high, forcing Y low and W high. It operates within a supply voltage range of 4.5 V to 5.5 V and an ambient temperature range of 0 °C to +70 °C. Propagation delays from data inputs to output range from 3 ns to 15 ns.
