Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'R2G' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status meets environmental regulations for the target market. Ensure the SOIC-16 footprint matches the PCB design specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch is required within a 16-pin surface-mount package. Consider the 100-ohm ON resistance limit for signal integrity requirements. Verify that the 2V to 6V digital supply range aligns with the system logic levels. Evaluate the 80MHz bandwidth capability against the highest frequency signals being routed through the multiplexer channels.
