FSA4157, FSA4157A
Low Voltage 1Ω SPDT Analog Switch
Features
■ FSA4157A features lower ICC when the S input is
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
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.
