74F675A
16-Bit Serial-In, Serial/Parallel-Out Shift Register
General Description
The 74F675A contains a 16-bit serial in/serial out shift reg-
ister and a 16-bit parallel out storage register. Separate
serial input and output pins are provided for expansion to
longer words. By means of a separate clock, the contents
of the shift register are transferred to the storage register.
The contents of the storage register can also be loaded
back into the shift register. A HIGH signal on the Chip
Select input prevents both shifting and parallel loading.
Features
s Serial-to-parallel converter
