8-bit static shift register
BU4021B / BU4021BF
The BU4021B and BU4021BF are 8-bit static shift registers consisting of 8 register cells, each of which has parallel input. Control of the parallel / serial control input (P / S) enables serial input / serial output with clock synchronization, as well as parallel input / serial output conversions.
