74HCT154D,653

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HCT154D,653 is a 4-to-16 line decoder/demultiplexer in the 74HCT logic family. It decodes four binary weighted address inputs (A0 to A3) into sixteen mutually exclusive active LOW outputs (Y0 to Y15). The device includes two active LOW enable inputs (E0 and E1); a HIGH level on either forces all outputs HIGH. It operates with a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. Packaged in a 24-lead SO plastic small outline package (SOT137-1), it supports an operating temperature range from -40 °C to +125 °C.
