Dual Per-Pin Parametric Measurement Units
AC ELECTRICAL CHARACTERISTICS (continued)
(VCC = +12V, VEE = -7V, VL = +3.3V, CCM = 120pF, CL = 100pF, TA = TMIN to TMAX, unless otherwise noted. TA < +25°C guaranteed
by design and characterization. Typical values are at TA = +25°C, unless otherwise specified.) (Note 2)
