DV is obtained as follows: Voltages of Q and Q* outputs with respect with V are measured. The absolute
OUT
EE
difference between the high and the low is equal to DV .
OUT
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 and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 1.7V.
(min)
250 mV minimum output peak-to-peak swing for Max Toggle Frequency.
Output test conditions: 100W termination resistor between Q and Q*.
