The FSA4157P6 is a single-pole double-throw (SPDT) high performance Analog Switch fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The select input is TTL level compatible. This feature services the mobile handset applications very well allowing for the direct interface with baseband processor general purpose I/Os.
Fast turn-on and turn-off time
Break-before-make enable circuitry
Over-voltage tolerant TTL-compatible control circuitry
