Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the Not Recommended for New Design (NRND) status before integration into new products. Confirm availability through authorized distributors as stock may be limited. Ensure compliance with RoHS directives by checking the detailed specification sheet. Validate that the MSOP-8 footprint matches the target PCB layout requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low voltage operation between 1.8 V and 5.5 V is required. The 4.5 Ohm on-resistance suits applications with moderate load currents up to 50 mA. Consider the MSOP-8 package for space-constrained designs requiring dual independent switches. Verify thermal management capabilities given the 320 mW power dissipation limit.
