Fairchild FSA2156 Low-voltage spst 0.4î© analog switch Datasheet

FSA2156 — Low-Voltage SPST 0.4Ω Analog Switch
Features
Description
ƒ Maximum 0.7Ω On Resistance (RON) for +2.7V
The FSA2156 is a high-performance Single-Pole
Single-Throw (SPST) analog switch that features ultra
low RON of 0.4Ω (typ.) at 2.7V VCC. The FSA2156
operates over the wide VCC range of 1.65V to 4.3V and
is fabricated with sub-micron CMOS technology to
achieve fast switching speeds. The select input is TTLlevel compatible.
Supply
ƒ 0.25Ω Maximum RON Flatness for +2.7V Supply
ƒ Space-Saving MicroPak™ and SC70 Packaging
ƒ Broad VCC Operating Range: 1.65 to 4.3V
ƒ Fast Turn-on and Turn-off Times
ƒ Over-Voltage Tolerant TTL-Compatible Control Input
ƒ Suitable for 2 UL USB2.0 Applications (200mA)
ƒ Low ICCT Current Over Expanded Control Input Range
FSA2156 features very low quiescent current even
when the control voltage is lower than the VCC supply.
This feature facilitates longer battery life in mobile
handset applications and allows for the direct interface
with baseband-processor, general-purpose I/Os.

FSA2156 — Low-Voltage SPST 0.4Ω Analog Switch
August 2007
Stresses exceeding the absolute maximum ratings may damage the device. 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.

Notes:
3. Guaranteed by characterization; not production tested.
4. On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
5. Flatness is defined as the difference between the maximum and minimum value of on resistance over the
specified range of conditions.
