DM74S151 1-of-8 Data Selector/Multiplexer with Complementary Outputs August 1986 Revised April 2000 DM74S151 1-of-8 Data Selector/Multiplexer with Complementary Outputs General Description These data selectors/multiplexers contain full on-chip decoding to select the desired data source. The DM74S151 selects one-of-eight data sources. The DM74S151 has a strobe input which must be at a low logic level to enable these devices. A high level at the strobe forces the W output HIGH and the Y output LOW. The DM74S151 features complementary W and Y outputs. Features s Select one-of-eight data lines s Performs parallel-to-serial conversion s Permits multiplexing from N lines to one line s Also for use as Boolean function generator s Typical average propagation delay time, data input to W output 4.5 ns s Typical power dissipation 225 mW Ordering Code: Order Number Package Number Package Description DM74S151N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Connection Diagram Function Table Inputs Select Strobe CBA S XXX H LLL L LLH L LHL L LHH L HLL L HLH L HH L L HHH L H = HIGH Level L = LOW Level X = Don’t Care D0, D1…D7 = The level of the respective D input Outputs YW LH D0 D0 D1 D1 D2 D2 D3 D3 D4 D4 D5 D5 D6 D6 D7 D7 © 2000 Fairchild Semiconductor Corporation DS006468 www.fairchildsemi.com DM74S151 Logic Diagram www.fairchildsemi.com 2 DM74S151 Absolute Maximum Ratings(Note 1) Supply Voltage 7V Input Voltage 5.5V Ope...
