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 the 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", the PARALLEL operation is designated and when it is "L", the SERIAL operation is designated.
