The FSA1256, FSA1256A, FSA1257, FSA1257A,
FSA1258, and FSA1258A are high performance dual
Single-Pole / Single-Throw (SPST) analog switches. All
devices feature ultra-low RON of 1.1 Ω maximum at 4.5 V
VCC. The FSA1256, FSA1257, and FSA1258 operate
over a wide VCC range of 1.65 V to 5.5 V. The
FSA1256A, FSA1257A, and FSA1258A operation range
is 2.7 V to 5.5 V. These devices are fabricated with submicron CMOS technology to achieve fast switching
speeds and are designed for break-before-make
operation. The select input is TTL level compatible. The
FSA1256 and FSA1256A feature two Normally Open
(NO) switches. The FSA1257 and FSA1257A feature
two Normally Closed (NC) switches. The FSA1258 and
FSA1258A have one NO switch and one NC switch.

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.

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