SN74HC164DR Shift Shift Register 1 Element 8 Bit 14-SOIC Logic IC

description

These 8-bit shift registers 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. A high-level input enables the

other input, which then determines the state of the

first flip-flop. Data at the serial inputs can be

changed while CLK is high or low, provided the

minimum setup time requirements are met.

Clocking occurs on the low-to-high-level transition

of CLK.
