NC7SB3157, FSA3157 Low Voltage SPDT Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch
General Description
The NC7SB3157 or FSA3157 is a high performance, single-pole/double-throw (SPDT) Analog Switch or 2:1 Multiplexer/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 VCC operating range. The control input tolerates voltages up to 5.5V independent of the VCC operating range.
Features
■ Useful in both analog and digital applications ■ Space saving SC70 6-lead surface mount package ■ Ultra small MicroPak™ Pb-Free leadless package ■ Low On Resistance; < 10Ω on typ @ 3.3V VCC ■ Broad VCC operating range; 1.65V to 5.5V ■ 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
