KK74ACT157 Datasheet | Kodenshi AUK Group

TECHNICAL DATA .. Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The KK74ACT157 is identical in pinout to the LS/ALS157, HC/HCT157. The KK74ACT157 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. 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 noninvertered form. A high level on the Output Enable input sets all four Y outputs to a low level. - TTL/NMOS patible Input Levels - Outputs Directly Interface to CMOS, NMOS, and TTL - Operating Voltage Range: 4.5 to 5.5 V - Low Input Current: 1.0 µA; 0.1 µA @ 25°C - Outputs Source/Sink 24 m A ORDERING INFORMATION KK74ACT157N Plastic KK74ACT157D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Output Enable PIN 16 =VCC PIN 8 = GND H L L Select X L H Outputs Y0-Y3 L A0-A3 B0-B3 X=don’t care A0-A3,B0-B3=the levels of the respective Data-Word Inputs ..
