FSA1156, FSA1157 Low-RON Low-Voltage SPST Analog Switch Features General Description ■ Maximum 0.9Ω RON for 4.5V Supply at 25°C The FSA1156 and FSA1157 are high-performance Single-Pole / Single-Throw (SPST) analog switches. The devices feature ultra-low RON of 0.75Ω (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. ■ 0.3Ω 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 MicroPak™ Space-saving, Surface-mount Packages Ordering Information Order Number Package Top Mark Number Package Description Packing Method FSA1156P6 MAA06A 156 6-Lead SC70, EIAJ SC88, 1.25mm Wide 250 Units Tape and Reel FSA1156P6X MAA06A 156 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3000 Units Tape and Reel FSA1156L6X MAC06A EH 6-Lead MicroPak, 1.0mm Wide 5000 Units Tape and Reel FSA1157P6 MAA06A 157 6-Lead SC70, EIAJ SC88, 1.25mm Wide 250 Units Tape and Reel FSA1157P6X MAA06A 157 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3000 UnitsTape and Reel FSA1157L6X MAC06A EJ 6-Lead MicroPak, 1.0mm Wide 5000 UnitsTape and Reel All packages are lead free per JEDEC: J-STD-020B standard.
