CD4014BM CD4014BC 8-Stage Static Shift Register
General Description
The CD4014BM CD4014BC is an 8-stage parallel input se-
rial output shift register A parallel serial control input en-
ables individual JAM inputs to each of 8 stages Q outputs
are available from the sixth seventh and eighth stages All
outputs have equal source and sink current capabilities and
conform to standard ‘‘B’’ series output drive
When the parallel serial control input is in the logical ‘‘0’’
state data is serially shifted into the register synchronously
with the positive transition of the clock When the parallel
serial control input is in the logical ‘‘1’’ state data is jammed
into each stage of the register synchronously with the posi-
tive transition of the clock
All inputs are protected against static discharge with diodes
to VDD and VSS
