74253 IC Dual 4-input multiplexer 3-state

Description

Description: Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections. The 3-STATE outputs can interface directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a HIGH or LOW logic level. Features: 3-STATE version of DM74LS153 with same pinout Schottky-diode-clamped transistors Permit multiplexing from N-lines to one line Performs parallel-to-serial conversion Strobe/output control High fanout totem-pole outputs Typical propagation delay Data to output 12 ns Select to output 21 ns Typical power dissipation 35 mW Recommended Operating Conditions: Symbol Parameter Min Nom Max Units VCC Supply Voltage 4.75 5 5.25 V VIH HIGH Level Input Voltage 2 V V IL LOW Level Input Voltage 0.8 V IOH HIGH Level Output Current −2.6 mA IOL LOW Level Output Current 24 mA T A Free Air Operating Temperature 0 70 °C Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol Parameter Conditions Min Typ Max Units V I Input Clamp Voltage V CC = Min, I I = −18 mA −1.5 V VOH HIGH Level Output Voltage V CC = Min, I OH = Max V IL = Max, V IH = Min 2.4 3.1 V VOL LOW Level Output Voltage V CC = Min, I OL = Max V IL = Max, V IH = Min 0.5 V I OL = 12 mA, V CC = Min 0.4 I I Input Current @ Max Input Voltage V CC = Max, V I = 7V 0.1 mA IIH HIGH Level Input Current V CC = Max, V I = 2.7V 20 µA IIL LOW Level Input Current V CC = Max, V I = 0.4V −0.4 mA IOZH Off-State Output Current with HIGH Level Output Voltage Applied V CC = Max, V O = 2.7V V IH = Min, V IL = Max 20 µA IOZL Off-State Output Current with LOW Level Output Voltage Applied V CC = Max, V O = 0.4 V IH = Min, V IL = Max −20 µA IOS Short Circuit Output Current V CC = Max (Note 3) −20 −100 mA ICC1 Supply Current V CC = Max (Note 4) 7 12 mA ICC2 Supply Current V CC = Max (Note 5) 8.5 14 mA IC Dimensions: Datasheet
