TC4021 - 8-STAGE STATIC SHIFT REGISTER
TC4021BP/BF/BFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC4021BP,TC4021BF,TC4021BFN 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,
