Part Description: CD4021BC 8-Stage Static Shift Register


Part Details:

CD402 October 1987 Revised March 2002 1BC 8- CD4021BC St 8-Stage Static Shift Register age Stat General Description Features The CD4021BC is an 8-stage parallel input/serial output s Wide supply voltage range: 3.0V to 15V shift register. A parallel/serial control input enables individ- ic Shi s High noise immunity: 0.45 VDD (typ.) ual JAM inputs to each of 8 stages. Q outputs are available s from the sixth, seventh, and eighth stages. All outputs have Low power TTL compatibility: equal source and sink current capabilities and conform to Fan out of 2 driving 74L or 1 driving 74LS f standard "B" series output drive. t s 5V­10V­15V parametric ratings Regi When the parallel/serial control input is in the logical "0" s Symmetrical output characteristics state, data is serially shifted into the register synchronously s Maximum input leakage 1 µA at 15V over full tempera- with the positive transition of the clock. When the parallel/ ture range ster serial control is in the logical "1" state, data is jammed intoeach stage of the register asynchronously with the clock. All inputs are protected against static discharge with diodesto VDD and VSS.
