The SN74HCS264 device contains an 8-bit shift register
with AND-gated serial inputs and an asynchronous clear
(CLR) input. Data at the serial inputs
can be changed while CLK is high or low, provided the minimum setup
time requirements are met. All inputs include Schmitt-trigger
architecture, adding noise margin and eliminating any input
transition rate requirement. Clocking occurs on the
low-to-high-level transition of CLK.
Upon a clock trigger, the device will store the result of the (A ● B) input data line in the first register and propagate each register’s data to the next register. The outputs are inverted from the data stored.
