Power-Off Isolation (VCC= 0V)
The FSA4159 is a high-performance Single-Pole /
Double-Throw (SPDT) analog switch. The device
features ultra-low RON of 1Ω at 4.5V VCC and operates
over the wide VCC range of 1.65V to 5.50V. The device
is fabricated with sub-micron CMOS technology to
achieve fast switching speeds and is designed for breakbefore-make operation.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
3. On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
4. ∆ RON=RON max – RON min measured at identical VCC, temperature and voltage.
5. Flatness is defined as the difference between the maximum and minimum value of on resistance over the
specified range of conditions.
