This document is a technical datasheet for the TOSHIBA TC4021BP, TC4021BF, and TC4021BFN integrated circuits. The device is described as an 8-stage static shift register that supports both asynchronous parallel input/serial output and serial input/serial output operations. Operation mode (parallel or serial) is controlled by the P/S CONTROL input.

Yes, the device can be configured for serial operations where each flip-flop is triggered by the rising edge of CLOCK.
It is an 8-stage static shift register that can be configured as a parallel-in/serial-out device or a serial-in/serial-out device.
The P/S CONTROL input determines the mode: a high level designates PARALLEL operation, while a low level designates SERIAL operation.
