SY10EL51

The SY10EL51/100EL51 are differential clock D flip-flops with reset. The SY10EL51 is functionally similar to the E151 devices, 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 SY10EL51 to be used as a negative edge triggered flip-flop.

The differential input of SY10EL51 employs clamp circuitry to maintain stability under open input (pulled down to VEE) conditions.
