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 f1irst flip-flop.
