The PI3A27518 is a 6-channel, 1:2 multiplexer/demultiplexer. The COMx port can be configured to connect with NOx or NCx ports in 4 different modes (refer to Truth Table for details). The PI3A27518 has a wide operating voltage range, very low power consumption and small packaging. The device can be used as an analog switch or as a low-delay bus switch. The PI3A27518 supports a wide operating power supply voltage, 1.65V to 3.6V and has an On-Resistance of 5Ω at +3.3V. Break-before-make switching prevents both switches from being enabled simultaneously. This eliminates signal disruption during switching.
