Description

The NC7SB3157 / FSA3157 is a high-performance, sin-

gle-pole / double-throw (SPDT) analog switch or 2:1 mul-

tiplexer / 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-before-

make select circuitry prevents disruption of signals on

the B Port due to both switches temporarily being

enabled during select pin switching. The device is speci-

fied to operate over the 1.65 to 5.5V V

operating

range. The control input tolerates voltages up to 5.5V,

independent of the V

operating range.

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. Symbol VCC Parameter Min.
