ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the specifi ed temperature range, otherwise specifi cations are at TA = 25°C. VS = 3V, 0V; VS = 5V, 0V, VCM = VOUT = half supply, for the 6-lead part VPIN5 = 0V, pulse power tested unless otherwise specifi ed. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
