DESCRIPTION
The SY10/100EP11U is a precision, high-speed 1:2
differential fanout buffer. Having within-device skews and
output transition times significantly improved over the
EL11V, the EP11U is ideally suited for those applications
which require the ultimate in AC performance.
The differential inputs of the EP11U employ clamping
circuitry to maintain stability under open input conditions.
If the inputs are left open, the Q outputs will go LOW.

Notes:
9. Measured with 750mV input signal, 50% duty cycle. All loading with a 50Ω to VCC –2.0V.
10. Skew is measured between outputs under identical transitions. Duty cycle skew is defined only for differential operation when the delays are
measured from the cross point of the inputs to the cross point of the outputs.
11. See “Input Waveform.”

Notes:
1. Power-saving alternative to Thevenin termination.
2. Place termination resistors as close to destination inputs as possible.
3. Rb resistor sets the DC bias voltage equal to Vt. For +3.3V systems Rb = 46Ω to 50Ω. For +5V systems, Rb = 110Ω.
