FSA2156 — Low-Voltage SPST 0.4Ω Analog Switch August 2007 FSA2156 — Low-Voltage SPST 0.4Ω Analog Switch Features Maximum 0.7Ω On Resistance (RON) for +2.7V Supply 0.25Ω Maximum RON Flatness for +2.7V Supply Space-Saving MicroPak™ and SC70 Packaging Broad VCC Operating Range: 1.65 to 4.3V Fast Turn-on and Turn-off Times Over-Voltage Tolerant TTL-Compatible Control Input Suitable for 2 UL USB2.0 Applications (200mA) Low ICCT Current Over Expanded Control Input Range Description 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. 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.

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. Symbol VCC VSW VCNTRL IIK ISW ISWPEAK PD TSTG TJ TL ESD Note: 1. The input and output negative ratings may be exceeded if the input and output diode current ratings are observed.
