MC10EP51, MC100EP51
3.3V / 5V ECL D Flip-Flop
with Reset and Differential
Clock
Description
The MC10/100EP51 is a differential clock D flip−flop with reset.
The device is functionally equivalent to the EL51 and LVEL51
devices.
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 EP51 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 conditions. When left open, the CLK input will be
pulled down to VEE and the CLK input will be biased at VCC/2.
The 100 Series contains temperature compensation.
