DM74LS153N

Revised March 2000 DM74LS153 Dual 1-of-4 Line Data Selectors/Multiplexers General Description Features Each of these data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR-invert gates. Separate strobe inputs are provided for each of the two four-line sections. ■ Permits multiplexing from N lines to 1 line ■ Performs at parallel-to-serial conversion ■ Strobe (enable) line provided for cascading (N lines to n lines) ■ High fan-out, low impedance, totem pole outputs ■ Typical average propagation delay times From data 14 ns From strobe 19 ns From select 22 ns ■ Typical power dissipation 31 mW Ordering Code: Order Number Package Number Package Description DM74LS153M M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow DM74LS153N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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. The “Recommended Operating Conditions” table will define the conditions for actual device operation. 7V Input Voltage 7V 0°C to +70°C Operating Free Air Temperature Range −65°C to +150° C Storage Temperature Range Recommended Operating Conditions Symbol Parameter Min Nom Max 4.75 5 5.25 Units VCC Supply Voltage VIH HIGH Level Input Voltage V VIL LOW Level Input Voltage 0.8 V IOH HIGH Level Output Current −0.4 mA IOL LOW Level Output Current 8 mA TA Free Air Operating Temperature 70 °C 2 V 0 Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol Parameter Conditions VI Input Clamp Voltage VCC = Min, II = −18 mA VOH HIGH Level VCC = Min, IOH = Max Output Voltage VIL = Max, VIH = Min VOL LOW Level VCC = Min, IOL = Max Output Voltage VIL = Max, VIH = Min Min Typ (Note 2) Max −1.5 2.7 IOL = 4 mA, VCC = Min 3.4 Units V V 0.35 0.5 0.25 0.4 V II Input Current @ Max Input Voltage VCC = Max, VI = 7V 0.1 IIH HIGH Level Input Current VCC = Max, VI = 2.7V 20 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −0.36 mA IOS Short Circuit Output Current VCC = Max (Note 3) −100 mA ICC Supply Current VCC = Max (Note 4) 10 mA −20 6.2 mA Note 2: All typicals are at VCC = 5V, TA = 25° C.
