| SL74HC164 8-Bit Serial-Input/Parallel-Output Shift Register High-Performance Silicon-Gate CMOS The SL74HC164 is identical in pinout to the LS/ALS164. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The SL74HC164 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 theClock 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 * High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HC164N Plastic SL74HC164D SOIC TA = -55 to 125 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Reset L H PIN 14 =VCC PIN 7 = GND H H Clock X A1 A2 XX XX HD DH 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 V ). CC Unused outputs must be left open.
