DESCRIPTION
The SY10EP52V is a differential data, differential clock
D flip-flop. The device is functionally equivalent to the
EL52 device.
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 EP52V allow the device to
be used as a negative edge triggered flip-flop
The EP52V employs input clamping circuitry so that
under open input condition (pulled down to V_EE) the
outputs of the device will remain stable.
