Integrated T1/E1/J1 Short-Haul and
Long-Haul Protection Switch
ELECTRICAL CHARACTERISTICS (continued)
(V+ = +2.7V to +3.6V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C, unless otherwise noted.) (Notes 2, 3)

Note 2: The algebraic convention is used in this data sheet. The most negative value is shown in the minimum column.
Note 3: Devices are 100% tested at hot and room and guaranteed by design at cold.
Note 4: ∆RON = RON(MAX) - RON(MIN).
Note 5: Guaranteed by design.
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_ or VNC_)], VCOM_ = output, VNO_ or VNC_ = input to off switch.
Note 8: Crosstalk between any two switches.
(V+ = 3.0V, TA = +25°C, unless otherwise noted.)
