FSA4157 Datasheet, PDF (1/14 Pages) Fairchild Semiconductor – Low Voltage 1OHM SPDT Analog Switch

March 2006
FSA4157, FSA4157A
Low Voltage 1Ω SPDT Analog Switch
Features
■ FSA4157A features lower I_CC when the S input is
lower than V_CC
■ Maximum 1.15Ω On Resistance (R_ON) at 4.5V V_CC
■ 0.3Ω max R_ON flatness at 4.5V V_CC
■ Space saving 6-lead Pb-Free MicroPak™ and
SC70 6-lead surface mount packages
■ Broad V_CC 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 R_ON of 1.15Ω 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 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 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.
