This 8-channel CMOS analog multiplexer and demultiplexer is designed for 1.65V to 5.5V VCC operation. The SN74LV4051A-Q1 handles analog and digital signals. Each channel permits signals with amplitudes up to 5.5V (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.
