Description
The FSA1259/FSA1259A is a high-performance, dual,
Single-Pole / Single-Throw (SPST) 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 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.

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.
