FSA4157

FSA4157, FSA4157A — Low-Voltage, 1  SPDT Analog Switch March 2014 FSA4157, FSA4157A Low-Voltage, 1  SPDT Analog Switch Features  FSA4157A Features Lower ICC when the S Input is Lower Than VCC  Maximum 1.15  On Resistance (RON) at 4.5 V VCC  0.3  Maximum RON Flatness at 4.5 V VCC  Space-Saving 6-lead, MicroPak™ and SC70 6 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 Description FSA4157 and FSA4157A are high performance Single Pole/Double Throw (SPDT) analog switches. Both devices feature ultra low RON of 1.15  maximum at 4.5 V VCC and operates over the wide VCC range of 1.65 V to 5.5 V for FSA4157, and 2.7 V to 5.5 V for FSA4157A. 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.
