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.
