| FSA3157B -- Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-Multiplexer Bus Switch January 2008 FSA3157B Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-multiplexer Bus Switch Features Useful in Both Analog and Digital Applications Ultra-small, MicroPakTM Leadless Package Low On Resistance: <10 Typical at 3.3V VCC Broad VCC Operating Range: 1.65V to 5.5V Rail-to-rail Signal Handling Power-down, High-impedance Control Input Over-voltage Tolerance of Control Input to 7.0V Break-before-make Enable Circuitry 250MHz, 3dB Bandwidth Description The FSA3157B is a high-performance, single-pole / double-throw (SPDT) analog switch or 2:1 multiplexer / de-multiplexer bus switch. The device is fabricated with advanced sub-micron CMOS technology to achieve high-speed enable and disable times and low on resistance. The break-beforemake select circuitry prevents disruption of signals on the B Port due to both switches temporarily being enabled during select pin switching. The device is specified to operate over the 1.65 to 5.5V VCC operating range. The control input tolerates voltages up to 5.5V, independent of the VCC operating range. Ordering Information Part Number FSA3157BL6X Operating Temperature Range -40 to +85C Top Mark 7G Package 6-Lead, MicroPak 1.0mm Wide Package Packing Method 5000 Units on Tape and Reel All packages are lead free per JEDEC: J-STD-020B standard.

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.
