Notes:

1. Parametric values specified at:

− 5V Power Supply Range:

100EL34 Series: −4.2V to −5.5V

10EL34 Series: −4.75V to −5.5V

− 3V Power Supply Range:

10/100EL34L Series: −3.0V to −3.8V

2. Skew is measured between outputs under identical transitions.

3. Minimum input swing for which AC parameters are guaranteed. The device will function reliably with differential inputs down to 100mV.

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 VPP minimum and 1V. The lower end of the CMR range varies 1:1 with VEE. The

numbers in the specification table assume a nominal VEE = −3.3V. Note for PECL operation, the VCMR(MIN) will be fixed at 3.3V − IVCMR(MIN)I.
