KK74ACT164

TECHNICAL DATA www.DataSheet4U.com KK74ACT164 8-Bit Serial-Input/Parallel-Output Shift register High-Speed Silicon-Gate CMOS The KK74ACT164 is identical in pinout to the LS/ALS164, HC/HCT164. The KK74ACT164 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74ACT164 is an 8-bit, serial-input to parallel-output shift register. Two serial data inputs, A1 and A2, are provided so that one input may be used as a data enable. Data is entered on each rising edge of the clock. The active-low asynchronous Reset overrides the Clock and Serial Data inputs. 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 KK74ACT164N Plastic KK74ACT164D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Reset L H H PIN 14 =VCC PIN 7 = GND Clock X A1 A2 X X X X H D L Outputs QA QB ...
