


The FSA1259A is a high-performance, dual, Single-Pole
/ Single-Throw (SPST) analog switch. The device
features ultra-low RON of 1  at 4.5 V VCC and operates
over the wide VCC range of 1.65 V to 5.50 V.
Power-Off Isolation (VCC=0 V)
1 Ω On Resistance (RON) for 4.5V VCC
0.25 Ω Maximum RON Flatness for 4.5 V VCC
Space-Saving, US8 Surface Mount Package
Broad VCC Operating Range: 1.65 V to 5.50 V
Fast Turn-On and Turn-Off Times
Break-Before-Make Enable Circuitry
The FS1259A allows for reduced input thresholds on the
select pins.
The device is fabricated with sub-micron CMOS
technology to achieve fast switching speeds and is
designed for break-before-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 the A and B pins at the indicated current through
the switch.
4. ∆RON=RON maximum – RON minimum; 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.
