This document describes the TC4021B series of 8-stage static shift registers manufactured by Toshiba. The device supports both asynchronous parallel input and synchronous serial input/serial output operations, with mode switching controlled via a P/S CONTROL pin.
The datasheet provides maximum ratings, recommended operating conditions, and detailed electrical characteristics including DC supply voltage ranges (3V to 18V), propagation delay times, clock frequency limits up to 24 MHz at 5V, and input/output current specifications. It also includes logic diagrams, truth tables, and outline drawings for DIP-16, SOP-16, and SOIC-16 packages.
| Supply Voltage Range | 3 to 18 V |
