This triple 2-channel CMOS analog multiplexer/demultiplexer is designed for 2-V to 5.5-V VCC operation. The SN74LV4053A handles both analog and digital signals. Each channel permits signals with amplitudes up to 5.5 V (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.
