Note 2: All parameters are production tested at TA = +25°C and guaranteed by design over the specified temperature range.
Note 3: Signals on COM_, NO_, or NC_ exceeding VCC are clamped by internal diodes. Limit forward-diode current to maximum
current ratings.
Note 4: Guaranteed by design; not production tested.
Note 5: ΔRON = RON(MAX) - RON(MIN).
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 7: Off-isolation = 20log10[VCOM_ / VNO_], VCOM_ = output, VNO_ = input to off switch.
