The SN74LV4051A 8-channel CMOS analog multiplexers and demultiplexers are designed for 1.65V to 5.5V VCC operation. The SN74LV4051A devices handle both 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.
