HI1-0548-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-0548-5 is a monolithic CMOS analog multiplexer manufactured by Renesas Electronics Corporation. It features an array of eight single-pole double-throw (SPDT) switches, controlled by a digital decoder circuit for channel selection. The device utilizes Dielectric Isolation (DI) process technology to eliminate latch-up issues and reduce substrate leakage. It includes an internal voltage reference for logic thresholds and an enable input for system expansion. The component is designed for harsh environment applications, supporting dual supply voltages typically ranging from ±10V to ±15V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm the exact screening flow, such as QML-V or MIL-STD-883 compliance. Ensure the package type matches the required form factor, typically CERDIP for this series. Confirm lead-free status and moisture sensitivity level requirements prior to ordering, as these vary by production lot and qualification standard.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high reliability and radiation tolerance are required for analog signal switching. The DI process makes it suitable for environments where conventional junction-isolated CMOS may fail due to latch-up. Verify that the supply voltage range and current consumption align with the system power budget. Consider the pin count and package dimensions for PCB layout constraints.
