FSA4157A

FSA4157, FSA4157A Low Voltage 1Ω SPDT Analog Switch March 2006 FSA4157, FSA4157A Low Voltage 1Ω SPDT Analog Switch Features ■ FSA4157A features lower ICC when the S input is ■ ■ ■ ■ General Description FSA4157 and FSA4157A are high performance Single Pole/Double Throw (SPDT) analog switches. Both devices feature ultra low RON of 1.15Ω maximum at 4.5V VCC and will operate over the wide VCC range of 1.65V to 5.5V for FSA4157, and 2.7V to 5.5V 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. ■ ■ ■ lower than VCC Maximum 1.15Ω On Resistance (RON) at 4.5V VCC 0.3Ω max RON flatness at 4.5V VCC Space saving 6-lead Pb-Free MicroPak™ and SC70 6-lead surface mount packages Broad VCC operating range: – FSA4157: 1.65V to 5.5V – FSA4157A: 2.7V to 5.5V Fast turn-on and turn-off time Break-before-make enable circuitry Over-voltage tolerant TTL compatible control circuitry 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.
