General Description
The FSA1156 and FSA1157 are high-performance Sin-
gle-Pole / Single-Throw (SPST) analog switches. The
devices feature ultra-low R_ON of 0.75Ω (typical) and
operate over a wide V_CC range of 1.65V to 5.5V. The
devices are fabricated with sub-micron CMOS technol-
ogy to achieve fast switching speeds. The select input is
TTL-level compatible. The FSA1156 has normally open
operation; the FSA1157 has normally closed operation.
