The MC10EL/100EL51 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.

1. Minimum input swing for which AC parameters are guaranteed.
2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within
the specified range and the peak-to-peak voltage lies between VPPmin and 1V. The lower end of the CMR range is dependent on VEE and is
equal to VEE + 2.5V.
