description/ordering information
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.
