ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the full specifi ed temperature range, otherwise specifi cations are at TA = 25°C or as noted. V+ = 2.7V to 5.5V, RL = 15k, CL = 5pF, Pin 4 = V+ unless otherwise noted. All voltages are with respect to GND. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
