| IN74ACT164 8-BIT SERIAL-INPUT/PARALLEL-OUTPUT SHIFT REGISTER High-Speed Silicon-Gate CMOS The IN74ACT164 is identical in pinout to the LS/ALS164, HC/HCT164. The IN74ACT164 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The IN74ACT164 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 A; 0.1 A @ 25C Outputs Source/Sink 24 mA * * * * ORDERING INFORMATION IN74ACT164N Plastic IN74ACT164D SOIC TA = -40 to 85 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Rese t L H H H Inputs Clock A1 A2 X X X H D X X D H Outputs QA QB ...

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND(VIN or VOUT)VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. 2 IN74ACT164 DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) VC Guaranteed Limits C Symbol VIH Parameter Test Conditions V 25 C Minimum High- VOUT=0.1 V or VCC-0.1 V 4.5 2.0 Level Input 5.5 2.0 Voltage VIL Maximum Low - VOUT=0.1 V or VCC-0.1 V 4.5 0.8 Level Input 5.5 0.8 Voltage VOH Minimum High- IOUT -50 A 4.5 4.4 Level Output 5.5 5.4 Voltage * VIN=VIH or VIL 3.86 IOH=-24 mA 4.5 4.86 5.5 IOH=-24 mA VOL Maximum Low- IOUT 50 A 4.5 0.1 Level Output 5.5 0.1 Voltage * VIN=VIH or VIL 0.36 IOL=24 mA 4.5 0.36 5.5 IOL=24 mA IIN Maximum Input VIN=VCC or GND 5.5 0.1 Leakage Current 5.5 Additional Max.
