SY10EP31V

Micrel 5V/3.3V, 3GHz PECL/LVPECL D FLIP-FLOP WITH SET AND RESET ECL Pro™ SY10EP31V SY10EP31V FINAL ECL Pro™ FEATURES s s s s s Guaranteed >3GHz bandwidth over temperature Guaranteed <440ps propagation delay 3.3V and 5V power supply options Wide operating temperature range: –40°C to +85°C Available in 8-pin (3mm) MSOP and SOIC package ECL Pro™ DESCRIPTION The SY10EP31V is a D flip-flop with set and reset. The device is pin and functionally equivalent to the EL31 and LVEL31 devices. With AC performance much faster than the EL31 and LVEL31 devices, the EP31V is ideal for applications requiring the fastest AC performance available. Both SET and RESET inputs are asynchronous, level triggered signals. 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.
