The 3.3V ELECTRICAL CHARACTERISTICS
l
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations are at TA = 25°C. V+ = 3.3V, GND = 0V, No RLOAD, CLOAD = 6pF. VCM = 1.25V, CLHI = V+, CLLO = 0V unless otherwise noted. VINCM is defi ned as (IN+ + IN–)/2. VOUTCM is defi ned as (OUT+ + OUT–)/2. VINDIFF is defi ned as (IN+ – IN–). VOUTDIFF is defi ned as (OUT+ – OUT–). See DC test circuit schematic. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS DC Clamping Characteristics
