Differential Data and
Clock D FlipĆFlop
The MC10EL/100EL52 is a differential data, differential clock D flip-flop
with reset. The device is functionally equivalent to the E452 device with
higher performance capabilities. With propagation delays and output
transition times significantly faster than the E452 the EL52 is ideally
suited for those applications which require the ultimate in AC
performance.
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 EL52 allow the
device to also be used as a negative edge triggered device.
The EL52 employs input clamping circuitry so that under open input
conditions (pulled down to VEE) the outputs of the device will remain
stable.

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.
3. The lower end of the CMR range is dependent on VEE and is equal to VEE + 2.5V.
