KK74AC158 Datasheet | Kodenshi AUK Group

TECHNICAL DATA .. Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The KK74AC158 is identical in pinout to the LS/ALS158, HC/HCT158. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALS 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; 0.1µA @ 25 °C - High Noise Immunity Characteristic of CMOS Devices - Outputs Source/Sink 24 m A ORDERING INFORMATION KK74AC158N Plastic KK74AC158D SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs PIN 16 =VCC PIN 8 = GND Output Enable H L L Select X L H Outputs Y0-Y3 H A0-A3 B0-B3 X=don’t care A0-A3,B0-B3=the levels of the respective Data-Word Inputs ..
