DESCRIPTION
■3.3V and 5V power supply options
■320ps typical propagation delay
■Maximum frequency > 3GHz typical
■75KΩinternal input pulldown resistor
■Transistor count: 143
■Available in 8-Pin (3mmx3mm) MSOP, SOIC and
MLF® (2mmx2mm) packages 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 VEE and the
/CLK input will be biased a VCC/2.
