The SY10EP51V is a D flip-flop with reset and
differential clock. The device is pin and functionally
equivalent to the EL51 device.
The reset input is an asynchronous, level triggered
signal. Data enters the master portion of the flip-flop
when CLK is LOW and is transferred to the slave, and
thus the outputs, upon a positive transition of the CLK.
The differential clock inputs of the EP51V 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 V
EE
and the
/CLK input will be biased a V
CC
/2.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation
is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM
RATlNG conditions for extended periods may affect device reliability.
