Features and Applications

The FSA4157P6X is a high performance Single Pole/Double Throw (SPDT) analog switch. This device feature ultra low RON of 1.15 Ω maximum at 4.5 V VCC and operates over a wide VCC range of 1.65 V to 5.5 V for FSA4157.

The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The select input is TTL level compatible. The FSA4157A features very low quiescent current even when the control voltage is lower than the VCC supply. This feature services the mobile handset applications very well allowing for the direct interface with baseband processor general purpose I/Os.


  • FSA4157A features lower ICC when the S input is lower than VCC
  • Maximum 1.15 ohm On Resistance (RON) at 4.5 V VCC
  • 0.3 ohm max RON flatness at 4.5 V VCC
  • Space saving 6-lead Pb-Free MicroPak™ and SC70 6-lead surface mount packages
  • Broad VCC operating range:
  • FSA4157: 1.65 V to 5.5 V
  • FSA4157A: 2.7 V to 5.5 V
  • Fast turn-on and turn-off time
  • Break-before-make enable circuitry
  • Over-voltage tolerant TTL compatible control circuitry
