100351
Low Power Hex D Flip-Flop
General Description
The 100351 contains six D-type edge-triggered, master/
slave flip-flops with true and complement outputs, a pair of
common Clock inputs (CPa and CPb) and common Master
Reset (MR) input. Data enters a master when both CPa and
CPb are LOW and transfers to the slave when CPa and CPb
(or both) go HIGH. The MR input overrides all other inputs
and makes the Q outputs LOW. All inputs have 50 kΩ
pull-down resistors.
