3 Description

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.
