| DM74150 Data Selectors/Multiplexers September 1986 Revised June 2001 DM74150 Data Selectors/Multiplexers General Description 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. The DM74150 features an inverted (W) output only. Features s 150 selects one-of-sixteen 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: 11 ns s 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-011, 0.600" Wide Connection Diagram Function Table Inputs Select D X L L L L L L L L H H H H H H H H C X L L L L H H H H L L L L H H H H B X L L H H L L H H L L H H L L H H A X L H L H L H L H L H L H L H L H Strobe S H L L L L L L L L L L L L L L L L H E0 E1 E2 E3 E4 E5 E6 E7 E8 E9 E10 E11 E12 E13 E14 E15 Outputs W H = HIGH Level L = LOW Level X = Don't Care E0, E1 ...E15 = the complement of the level of the respective E input (c) 2001 Fairchild Semiconductor Corporation DS006546 www.fairchildsemi.com DM74150 Logic Diagram www.fairchildsemi.com 2 DM74150 Absolute Maximum Ratings(Note 1) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 5.5V 0C to +70C 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. -65C to +150C Recommended Operating Conditions Symbol VCC VIH VIL IOH IOL TA Parameter Supply Voltage HIGH Level Input Voltage LOW Level Input Voltage HIGH Level Output Current LOW Level Output Current Free Air Operating Temperature 0 Min 4.75 2 0.8 Nom 5 Max 5.25 Units V V V mA mA -0.8 16 70 C Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol VI VOH VOL II IIH IIL IOS ICC Parameter Input Clamp Voltage HIGH Level Output Voltage LOW Level Output Voltage Input Current @ Max Input Voltage HIGH Level Input Current LOW Level Input Current Short Circuit Output Current Supply Current Conditions VCC = Min, II = -12 mA VCC = Min, IOH = Max VIL = Max, VIH = Min VCC = Min, IOL = Max VIH = Min, VIL = Max VCC = Max, VI = 5.5V VCC = Max, VI = 2.4V VCC = Max, VI = 0.4V VCC = Max (Note 3) VCC = Max (Note 4) -18 40 2.4 0.4 1 40 -1.6 -55 68 Min Typ (Note 2) Max -1.5 Units V V V mA A mA mA mA Note 2: All typicals are at VCC = 5V, TA = 25C.
