IN74AC164 8-Bit Serial-Input/Parallel-Output Shift register High-Speed Silicon-Gate CMOS • • • • • The IN74AC164 is identical in pinout to the LS/ALS164, HC/HCT164. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The IN74AC164 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. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 µA; 0.1 µA @ 25°C High Noise Immunity Characteristic of CMOS Devices Outputs Source/Sink 24 mA LOGIC DIAGRAM ORDERING INFORMATION IN74AC164N Plastic IN74AC164D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT FUNCTION TABLE Inputs Outputs Res Clock A1 A2 QA QB ... et QH L X X X L L ...

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 IN74AC164 DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) Guaranteed VCC Limits Symbol Parameter Test Conditions V 25 °C -40°C to 85°C 2.1 2.1 VIH Minimum High- VOUT=0.1 V or VCC-0.1 V 3.0 3.15 3.15 Level Input 4.5 3.85 3.85 Voltage 5.5 0.9 0.9 VIL Maximum Low - VOUT=0.1 V or VCC-0.1 V 3.0 1.35 1.35 Level Input 4.5 1.65 1.65 Voltage 5.5 2.9 2.9 VOH Minimum High- IOUT ≤ -50 µA 3.0 4.4 4.4 Level Output 4.5 5.4 5.4 Voltage 5.5 * VIN=VIH or VIL 2.46 2.56 IOH=-12 mA 3.0 3.76 3.86 IOH=-24 mA 4.5 4.76 4.86 5.5 IOH=-24 mA 0.1 0.1 VOL Maximum Low- IOUT ≤ 50 µA 3.0 0.1 0.1 Level Output 4.5 0.1 0.1 Voltage 5.5 * VIN=VIH or VIL 0.44 0.36 IOL=12 mA 3.0 0.44 0.36 IOL=24 mA 4.5 0.44 0.36 5.5 IOL=24 mA IIN Maximum Input VIN=VCC or GND 5.5 ±0.1 ±1.0 Leakage Current VOLD=1.65 V Max IOLD +Minimum 5.5 75 Dynamic Output Current VOHD=3.85 V Min IOHD +Minimum 5.5 -75 Dynamic Output Current VIN=VCC or GND ICC Maximum 5.5 4.0 40 Quiescent Supply Current (per Package) * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time.
