SN54/74LS322A 8-BIT SHIFT REGISTERS WITH SIGN EXTEND These 8-bit shift registers have multiplexed input/output data ports to accomplish full 8-bit data handling in a single 20-pin package.
Serial data may enter the shift-right register through either D0 or D1 inputs as selected by the data select pin.
A serial output is also provided.
Synchronous parallel loading is achieved by taking the register enable and the S / P inputs low.
This places the three-state input / output ports in the data input mode.
Data is entered on the low-to-high clock transition.
The data extend function repeats the sign in the QA flip-flop during shifting.
An overriding clear input clears the internal registers when ...
