74HC154; 74HCT154; 4-to-16 line decoder/demultiplexer
General descriptionThe 74HC154; 74HCT154 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL).
The 74HC154; 74HCT154 decoders accept four active HIGH binary address inputs and
provide16 mutually-exclusive active LOW outputs. The two-input enable gate canbe used strobe the decoderto eliminate the normal decoding ‘glitches’on the outputs,or canbe
used for the expansion of the decoder.
The enable gate has two ANDed inputs which must be LOW to enable the outputs.
The 74HC154; 74HCT154 can be used as a 1-to-16 demultiplexer by using one of the
enable inputs as the multiplexed data input.
When the other enable input is LOW, the addressed output will follow the state of the
applied data. Features 16-line demultiplexing capability Decodes 4 binary-coded inputs into 16 mutually-exclusive outputs Complies with JEDEC standard no. 7A Specified from −40 °C to +85 °C and −40 °C to +125°C ESD protection: HBM EIA/JESD22-A114D exceeds 2000V MM EIA/JESD22-A115-A exceeds 200V Ordering information
