Dual Type D Master-Slave
Flip-Flop
The MC10131 is a dual masterâslave type D flipâflop. Asynchronous Set (S)
and Reset (R) override Clock (CC) and Clock Enable (CE) inputs. Each flipâflop
may be clocked separately by holding the common clock in the low state and
using the enable inputs for the clocking function. If the common clock is to be
used to clock the flipâflop, the Clock Enable inputs must be in the low state. In
this case, the enable inputs perform the function of controlling the common
clock.
The output states of the flipâflop change on the positive transition of the
clock. A change in the information present at the data (D) input will not affect the
output information at any other time due to master slave construction.
PD = 235 mW typ/pkg (No Load)
FTog = 160 MHz typ
tpd = 3.0 ns typ
tr, tf = 2.5 ns typ (20%â80%)
