1 / 14 page  March 2006 ©2006 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FSA4157, FSA4157A Rev. 1.0.1 FSA4157, FSA4157A Low Voltage 1 Ω SPDT Analog Switch Features ■ FSA4157A features lower ICC when the S input is lower than VCC ■ Maximum 1.15 Ω On Resistance (R ON) at 4.5V VCC ■ 0.3 Ω max R ON 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 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. 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. Ordering Information Pb-Free package per JEDEC J-STD-020B. Note: 1. “_NL” indicates lead-free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
