| 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 A; 0.1 A @ 25C High Noise Immunity Characteristic of CMOS Devices Outputs Source/Sink 24 mA * * * * * ORDERING INFORMATION IN74AC164N Plastic IN74AC164D SOIC TA = -40 to 85 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM PIN 14 =VCC PIN 7 = GND FUNCTION TABLE Inputs Outputs Res Clock A1 A2 QA QB ... et QH L X XX 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 -40C to 85C 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 A 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 A 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.
