KK74ACT158

TECHNICAL DATA www.DataSheet4U.com KK74ACT158 Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The KK74ACT158 is identical in pinout to the LS/ALS138, HC/HCT138. The KK74ACT158 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 invertered form. A high level on the Output Enable input sets all four Y outputs to a high level. TTL/NMOS Compatible 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 mA ORDERING INFORMATION KK74ACT158N Plastic KK74ACT158D 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 1 www.DataSheet4U.com KK74ACT158 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SO...
