INTEGRATED CIRCUITS DATA SHEET 74HC154; 74HCT154 4-to-16 line decoder/demultiplexer Product specication Supersedes data of 2004 Oct 05 2004 Oct 12 Philips Semiconductors Product specication 4-to-16 line decoder/demultiplexer FEATURES 16-line demultiplexing capability Decodes 4 binary-coded inputs into one 16 mutually exclusive outputs Complies with JEDEC standard no. 8-1 B ESD protection: HBM EIA/JESD22-A114-B exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. Specified from 40 °C to +85 °C and 40 °C to +125 °C. DESCRIPTION 74HC154; 74HCT154 The 74HC154; 74HCT154 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC154; 74HCT154 decoders accept four active HIGH binary address inputs and provide 16 mutually exclusive active LOW outputs. The two-input enable gate can be used to strobe the decoder to eliminate the normal decoding “glitches” on the outputs, or can be 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. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns.
