FAST AND LS TTL DATA
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 taken low whether the outputs are enabled or off. The output
enable does not affect synchronous operation of the register.
