No Preview Available ! TECHNICAL DATA Quad 2-Input Data Selectors/Multiplexers High-Performance Silicon-Gate CMOS IN74HC158A The IN74HC158A is identical in pinout to the LS/ALS158. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in invertered form. A high level on the Output Enable input sets all four Y outputs to a high level. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION IN74HC158AN Plastic IN74HC158AD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 16 =VCC www.datasheet4u.PcINo8m= GND FUNCTION TABLE Inputs Outputs Output Enable Select Y0-Y3 H XH L L A0-A3 L H B0-B3 X=don’t care A0-A3,B0-B3=the levels of the respective Data-Word Inputs 1 1 page IN74HC158A EXPANDED LOGIC DIAGRAM 5 5 Page
