Revised February 2000 DM74150 Data Selectors/Multiplexers General Description Features These data selectors/multiplexers contain full on-chip decoding to select the desired data source. The DM74150 selects one-of-sixteen data sources. The DM74150 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 (as applicable) LOW. ■ 150 selects one-of-sixteen data lines The DM74150 features an inverted (W) output only. ■ Performs parallel-to-serial conversion ■ Permits multiplexing from N lines to one line ■ Also for use as Boolean function generator ■ Typical average propagation delay time, data input to W output: 11 ns ■ Typical power dissipation: 200 mW Ordering Code: Order Number DM74150N Package Number N24A Package Description 24-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-010, 0.600 Wide Connection Diagram Function Table Inputs Outputs Select Strobe W D C B A S X X X X H H L L L L L E0 L L L H L E1 L L H L L E2 L L H H L E3 L H L L L E4 L H L H L E5 L H H L L E6 L H H H L E7 H L L L L E8 H L L H L E9 H L H L L E10 H L H H L E11 H H L L L E12 H H L H L E13 H H H L L E14 H H H H L E15 H = HIGH Level L = LOW Level X = Don’t Care E0, E1 …E15 = the complement of the level of the respective E input © 2000 Fairchild Semiconductor Corporation DS006546 www.fairchildsemi.com DM74150 Data Selectors/Multiplexers September 1986 DM74150 Logic Diagram www.fairchildsemi.com 2 Supply Voltage 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. The “Recommended Operating Conditions” table will define the conditions for actual device operation. 7V Input Voltage 5.5V 0°C to +70°C Operating Free Air Temperature Range Storage Temperature Range −65°C to +150°C Recommended Operating Conditions Symbol Parameter Min Nom Max Units 4.75 5 5.25 V LOW Level Input Voltage 0.8 V IOH HIGH Level Output Current −0.8 mA IOL LOW Level Output Current 16 mA TA Free Air Operating Temperature 70 °C VCC Supply Voltage VIH HIGH Level Input Voltage VIL 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 = −12 mA VOH HIGH Level VCC = Min, IOH = Max Output Voltage VIL = Max, VIH = Min VOL LOW Level VCC = Min, IOL = Max Output Voltage VIH = Min, VIL = Max Min Typ (Note 2) Max Units −1.5 V 2.4 V 0.4 V mA II Input Current @ Max Input Voltage VCC = Max, VI = 5.5V 1 IIH HIGH Level Input Current VCC = Max, VI = 2.4V 40 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −1.6 mA IOS Short Circuit Output Current VCC = Max (Note 3) ICC Supply Current VCC = Max (Note 4) −18 40 −55 mA 68 mA Note 2: All typicals are at VCC = 5V, TA = 25°C.
