Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that original Harris semiconductor assets were acquired by other entities. Confirm the package type is the 20-pin LDCC variant and check RoHS compliance status, as older Harris components may not meet current environmental standards. Ensure the supply voltage requirements align with system design specifications before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an eight-channel analog switch is required with CMOS compatibility. Verify that the 1000 Ω on-state resistance meets the application's signal integrity needs. Consider the 15 V supply requirement and ensure the 70 °C maximum operating temperature is sufficient for the intended environment. Compare against newer equivalents if higher performance or modern packaging is desired.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI4 series of analog multiplexers produced by Harris Semiconductor. The series typically includes various channel counts and package options. Harris Corporation was a significant player in the semiconductor industry before its assets were divested, leading to complex ownership histories for these legacy parts. The HI4-0518-8 specifically represents an eight-channel configuration in a plastic leaded chip carrier package.
