| FSA1156, FSA1157 -- Low RON Low-Voltage SPST Analog Switch January 2008 FSA1156, FSA1157 Low-RON Low-Voltage SPST Analog Switch Features Maximum 0.9 RON for 4.5V Supply at 25C 0.3 Maximum RON Flatness for 4.5V Supply Broad VCC Operating Range: 1.65V to 5.5V Fast Turn-on and Turn-off Time Over-voltage Tolerant, TTL-compatible Control Input Available in SC70 and MicroPakTM Space-saving, General Description The FSA1156 and FSA1157 are high-performance Single-Pole / Single-Throw (SPST) analog switches. The devices feature ultra-low RON of 0.75 (typical) and operate over a wide VCC range of 1.65V to 5.5V. The devices are fabricated with sub-micron CMOS technology to achieve fast switching speeds. The select input is TTL-level compatible. The FSA1156 has normally open operation; the FSA1157 has normally closed operation.

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.
