Note 1: UCSP and TDFN parts are 100% tested at TA = +25°C only, and guaranteed by design over the specified temperature
range.
Note 2: Signals on COM_, NO_, or NC exceeding VCC are clamped by internal diodes. Limit forward-diode current to maximum cur-
rent rating.
Note 3: Guaranteed by design.
Note 4: ICOM for UCSP is 10mA.
Note 5:
RON = 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: The MAX4902/MAX4904/MAX4905 have an internal shunt resistor when, in off-state, will determine off-current.
Note 8: Off-Isolation = 20log10 (VCOM / VNO), VCOM = output, VNO = 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, unless other-
wise noted.) (Note 1)
