SN74LVC1G3157, SPDT Analog Switches

Texas Instruments' SN74LVC1G3157, single-pole, double-throw (SPDT) analog switches are designed for 1.65 VCC to 5.5 VCC operations. The SN74LVC1G3157 devices can handle both analog and digital signals. The SN74LVC1G3157 devices permit signals with amplitudes of up to VCC (peak) to be transmitted in either direction.

Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.

Features
  • 1.65 VCC to 5.5 VCC operation
