NC7SB3157, FSA3157
Low Voltage SPDT Analog Switch or
2:1 Multiplexer/Demultiplexer Bus Switch
General Description
The NC7SB3157 or FSA3157 is a high performance, sin-
gle-pole/double-throw (SPDT) Analog Switch or 2:1 Mul-
tiplexer/Demultiplexer 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 specified to operate over the
1.65 to 5.5V V_CC operating range. The control input toler-
ates voltages up to 5.5V independent of the V_CC operat-
ing range.
Features

■ Rail-to-Rail signal handling
■ Power down high impedance control input
■ Overvoltage tolerance of control input to 7.0V
■ Break before make enable circuitry
■ 250 MHz, 3dB bandwidth
