3 Description
The SN74HCS264-Q1 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.
