Description
FSA4157 and FSA4157A are high performance Single Pole/Double Throw (SPDT) analog switches. Both devices feature ultra low R ON of 1.15 Ω maximum at 4.5V V CC and will operate over the wide V CC range of 1.65V to 5.5V for FSA4157, and 2.7V to 5.5V for FSA4157A. The device is f abricated 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 V CC supply. This feature services the mobile handset applications very well allowing for the direct interface with baseband processor general purpose I/Os. Technology Description The Fairchild Switch family derives from and embodies Fairchild’s proven switch technology used for several years in its 74LVXL384 (FST3384) bus switch product.

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. Symbol Parameter Min. Max.

Measured by the voltage drop between the A and B pins at the indicated current through the switch. On resistance is determined by the lower of the voltage on the two (A or B ports). 5. ΔRON = RON max – RON min measured at identical VCC, temperature, and voltage. 6. Flatness is defined as the difference between the maximum and minimum value of on resistance over the specified range of conditions.
