MC10EL51, MC100EL51
5VꢀECL Differential Clock D
Flip-Flop
Description
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.
