SY100EL51 DESCRIPTION FEATURES ■ ■ ■ ■ SY10EL51 SY100EL51 SY10EL51 DIFFERENTIAL CLOCK D FLIP-FLOP Micrel, Inc. 475ps propagation delay 2.8GHz toggle frequency Internal 75KΩ input pull-down resistors Available in 8-pin SOIC package The SY10/100EL51 are differential clock D flip-flops with reset. These devices are functionally similar to the E151 devices, with higher performance capabilities. With propagation delays and output transition times significantly faster than the E151, the EL51 is ideally suited for those applications which require the ultimate in AC performance. 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 EL51 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 (pulled down to VEE) conditions.

Minimum input swing for which AC parameters are guaranteed. 2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP min. and 1V. The lower end of the CMR range is dependent on VEE and is equal to VEE + 3.0V.
