The EL51 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 the master portion of the flip-flop when the clock is LOW and is transferred to the slave, and thus the outputs, upon a positive transition of the clock. The differential clock inputs of the EL51 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 VEE) conditions.
The MC10EL51 and MC100EL51 are differential clock D flip-flops with reset, designed for applications requiring ultimate AC performance. These devices are functionally similar to the E151 but offer significantly faster propagation delays and output transition times. The reset input is asynchronous and level-triggered, allowing data to enter the master portion when the clock is LOW and transfer to the slave upon a positive clock transition.
