Low Voltage
1:2 Differential Fanout Buffer
The MC100LVEL11 is a differential 1:2 fanout buffer. The device is
functionally similar to the E111 device but with higher performance
capabilities. Having within-device skews and output transition times
significantly improved over the E111, the LVEL11 is ideally suited for
those applications which require the ultimate in AC performance.
The differential inputs of the LVEL11 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.

1. Within-device skew defined as identical transitions on similar paths through a device.
2. Duty cycle skew is the difference between a TPLH and TPHL propagation delay through a device.
3. Minimum input swing for which AC parameters guaranteed. The device will function properly with input swings below 200mV, however, AC
delays may move outside of the specified range. The device has a DC gain of 40.
4. 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 VPPmin and 1V. The lower end of the CMR range varies 1:1 with VEE. The number
in the spec table assumes a nominal VEE = –3.3V. Note for PECL operation, the VCMR(min) will be fixed at 3.3V – |VCMR(min)|.
