MC10EP131/D
MC10EP131, MC100EP131
3.3V / 5VECL Quad D
Flip−Flop with Set, Reset,
and Differential Clock
Description
The MC10/100EP131 is a Quad Master−slaved D flip−flop with
common set and separate resets. The device is an expansion of the
E131 with differential common clock and individual clock enables.
With AC performance faster than the E131 device, the EP131 is ideal
for applications requiring the fastest AC performance available.
Each flip−flop may be clocked separately by holding Common
Clock (C
C
) LOW and C
C
HIGH, then using the differential Clock
Enable inputs for clocking (C
0−3
, C
0−3
).
Common clocking is achieved by holding the differential inputs
C
0−3
LOW and C
0−3
HIGH while using the differential Common
Clock (C
C
) to clock all four flip−flops. When left floating open, any
differential input will disable operation due to input pulldown resistors
forcing an output default state.
Individual asynchronous resets (R
0−3
) and an asynchronous set
(SET) are provided.
Data enters the master when both C
C
and C
0−3
are LOW, and
transfers to the slave when either C
C
or C
0−3
(or both) go HIGH.
The 100 Series contains temperature compensation.
