DM74LS151 Datasheet | Fairchild Semiconductor

Description This data selector/multiplexer contains full on-chip decoding to select the desired data source. The DM74LS151 selects one-of-eight data sources. The DM74LS151 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 DM74LS151 features plementary 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 12.5 ns s Typical power dissipation 30 m W Ordering Code: Order Number DM74LS151M DM74LS151SJ DM74LS151N Package Number M16A M16D N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.

Absolute Maximum Ratings(Note 1) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 7V 0°C to +70°C - 65°C to +150°C Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings....
