SN74HC164D 8Bit Shift Register Module feature AND-gated serial inputs and an asynchronous clear (CLR) input. The gated serial (A and B) inputs permit complete control over incoming data; a low at either input inhibits entry of the new data and resets the first flip-flop to the low level at the next clock (CLK) pulse.
Features of SN74HC164D 8bit Shift Register Module:
Wide operating voltage range of 2V to 6V.
AND-Gated (enable/disable)serial inputs.
Fully buffered clock and serial inputs.
