MC74HC164B
8-Bit Serial-Input/ParallelOutput Shift Register
High−Performance Silicon−Gate CMOS
The MC74HC164B is identical in pinout to the LS164. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The MC74HC164B 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. Schmitt−trigger action at the Clock input enhances the device’s tolerance to slower rise and fall times and immunity to noise of the input clock signal.
