HI4P0508-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI4P0508-5 is a monolithic CMOS analog multiplexer manufactured by Intersil, now part of Renesas Electronics. It integrates an array of eight single-ended analog switches with a digital decoder circuit for channel selection and an enable input. The device utilizes Dielectric Isolation (DI) technology to eliminate latch-up issues and reduce substrate leakage compared to conventional junction-isolated CMOS. It supports wide analog signal ranges and offers low on-resistance characteristics suitable for precision applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential obsolescence status. Check RoHS compliance markings as variants exist. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Validate datasheet revisions against current engineering requirements before integration into new designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when eight-channel single-ended multiplexing is required with high reliability. The DI process makes it suitable for harsh environments where latch-up is a concern. Ensure supply voltage limits accommodate the ±15V range. Consider pinout compatibility if replacing legacy Harris or Intersil parts in existing PCB layouts.
