SN74LVC1G3157DBVR

This single-pole, double-throw (SPDT) analog switch is designed for 1.65-V to 5.5–VCC operation. The SN74LVC1G3157 can handle both analog and digital signals. The device permits signals with amplitudes of up to VCC (peak) to be transmitted in either direction.

Applications

• signal gating
• chopping
• modulation or demodulation (modem)
• signal multiplexing for analog-to-digital and digital-to-analog conversion systems
