| FSA2257 Low RON Low-Voltage Dual SPDT Bi-Directional Analog Switch January 2007 FSA2257 Low RON Low-Voltage Dual SPDT Bi-Directional Analog Switch Features Maximum 1.15 On Resistance (RON) for 4.5V Supply 0.3 Maximum RON Flatness for +5V Supply Space-Saving Pb-Free MicroPakTM 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 Description 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 1.3 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.
