MC100EL51

The MC100EL51 is a differential clock D flip-flop with reset. The device is functionally similar to the E151 device with higher performance capabilities. With propagation delays and output transition times significantly faster than the E151 the EL51 is ideally suited for those applications which require the ultimate in AC performance.

The reset input is an asynchronous, level triggered signal. Data enters he master portion of the flip-flop when the clock is LOW and is ransferred to the slave, and thus the outputs, upon a positive transition of he clock. The differential clock inputs of the MC100EL51 allow the device to be used as a negative edge triggered flip-flop.

The differential input employs clamp circuitry to maintain stability under open input (pulled down to V_EE ) conditions.
