TC4021B 8-Stage Static Shift Register
(asynchronous parallel input or synchronous serial
input/serial output)
TC4021B is 8 stage parallel in/serial out shift register, which
can be used also for serial in/serial out operations. In the case of
parallel operation, the data of PARALLEL IN is input to each F/F
asynchronously with CLOCK and the output is obtained. In the
case of serial operations, each F/F is triggered by rising edge of
CLOCK. (asynchronous parallel or synchronous serial input)
Switching of PARALLEL operation and SERIAL operation is
achieved by P/ S CONTROL input. When P/ S CONTROL input
is “H”, PARALLEL operation is designated and when it is “L”,
SERIAL operation is designated.
Pin Assignment
Note: xxxFN (JEDEC SOP) is not available in
Japan.
