FSA2257 Low RON Low-Voltage Dual SPDT
Bi-Directional Analog Switch
Features
Description
■ Maximum 1.15Ω On Resistance (RON) for 4.5V Supply
The FSA2257 is a high-performance bi-directional dual
Single-Pole/Double-Throw (SPDT) analog switch. This
switch can be configured as either a multiplexer or a demultiplexer by select pins. The device features ultra-low
RON of 1.3Ω maximum at 4.5V VCC and operates over
the wide VCC range of 1.65V to 5.5V. The device is fabricated with submicron CMOS technology to achieve fast
switching speeds and is designed for break-before-make
operation. The select input is TTL-level compatible.
■ 0.3Ω Maximum RON Flatness for +5V Supply
■ Space-Saving Pb-Free MicroPak™ Packaging
■ Broad VCC Operating Range: 1.65V to 5.5V
■ Fast Turn-on / Turn-off Time
■ Break-Before-Make Enable Circuitry
■ Over-Voltage Tolerant TTL-Compatible Control Input
Applications
■ Cell Phone
■ PDA
■ Ultra-Portable

Connection Diagrams
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:
4. On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
5. ΔRON = RONmax – RONmin measured at identical VCC, temperature, and voltage.
6. Flatness is defined as the difference between the maximum and minimum value of on resistance over the specified
range of conditions.
