Note 1: All parameters are production tested at TA = +25°C and guaranteed by design over the specified temperature range.
Note 2: Signals on X, Y, X_, or Y_ exceeding VCC are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Note 3: Guaranteed by design; not production tested.
Note 4: ΔRON = RON(MAX) – RON(MIN).
Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified
analog signal ranges.
Note 6: X Off-Isolation = 20log10 [VX / VX_], VX = output, VX_ = input to off switch. Y Off-Isolation = 20log10 [VY / VY_], VY = output,
VY_ = input to off switch.
ELECTRICAL CHARACTERISTICS (continued)
(VCC = +2.7V to +5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +3.0V, TA = +25°C.) (Note 1)
