| 5V/3.3V 1:2 DIFFERENTIAL FANOUT BUFFER FEATURES s s s s s s s s 3.3V and 5V power supply options 265ps propagation delay 5ps skew between outputs High bandwidth output transitions Internal 75K input pull-down resistors Replaces SY10/100EL11 Improved output waveform characteristics Available in 8-pin SOIC package ClockWorksTM SY10EL11V SY100EL11V DESCRIPTION The SY10/100EL11V are 1:2 differential fanout gates. These devices are functionally similar to the E111A/L devices, with higher performance capabilities. Having within-device skews and output transition times significantly improved over the E111A/L, the EL11V is ideally suited for those applications which require the ultimate in AC performance. The differential inputs of the EL11V employ clamping circuitry to maintain stability under open input conditions. If the inputs are left open (pulled to VEE), the Q outputs will go LOW.

Parametric values specified at: 10/100EL11V Series: -3.0V to -5.5V. 2. Within-device skew defined as identical transitions on similar paths through a device. 3. Duty cycle skew is the difference between a tPLH and tPHL propagation delay through a device. 4. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of 40. 5. 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 varies 1:1 with VEE. The numbers in the spec table assume a nominal VEE = -3.3V. Note for PECL operation, the VCMR (min) will be fixed at 3.3V - |VCMR (min)|.
