Features & Applications

The MC100EP131 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 (CC) LOW and CC HIGH, then using the differential Clock Enable inputs for clocking (C0−3, C0−3). Common clocking is achieved by holding the differential inputs C0−3 LOW and C0−3 HIGH while using the differential Common Clock (CC) 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 (R0−3) and an asynchronous set (SET) are provided. Data enters the master when both CC and C0−3 are LOW, and transfers to the slave when either CC or C0−3 (or both) go HIGH. The 100 Series contains temperature compensation.
