Device specification limit values are applied individually under normal operating conditions and not valid simultaneously. Input and output parameters vary 1:1 with VCC. VEE can vary +0.25 V / –0.5 V. Outputs are terminated through a 50-Ω resistor to VCC – 2 V. VIHCMR min varies 1:1 with VEE; VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the more-positive side of the differential input signal.
