HI30300-5

Analog Switches, Multiplexers, Demultiplexers Overview

The HI30300-5 is a monolithic analog switch integrated circuit fabricated using CMOS technology and the Harris dielectric isolation process. It contains two independent single-pole single-throw (SPST) switches within a single package. The device features an on-resistance of 50 Ohms, supporting analog signal switching with low distortion. It is housed in a 14-pin Dual In-line Package (PDIP) with a standard pin spacing of 0.300 inches (7.62 mm). The component is designed for through-hole mounting and operates as part of the HI-300 series interface ICs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic CMOS construction utilizing Harris dielectric isolation for enhanced performance
• Dual SPST configuration providing two independent switching channels
• Low on-resistance characteristic suitable for precision analog signal routing

Analog Switches, Multiplexers, Demultiplexers Applications

• Analog signal multiplexing and demultiplexing
• Data acquisition systems requiring low-distortion switching
• Instrumentation circuits needing precise analog path selection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Ensure the specific lot date code aligns with current supply chain availability. Confirm that the 14-DIP package matches the required PCB footprint and that the RoHS status is acceptable for the target assembly process, noting that older Harris parts may not be fully compliant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated analog switches are required in a through-hole DIP format. The 50 Ohm on-resistance makes it suitable for general-purpose analog switching rather than high-frequency RF applications. Consider the 14-pin package size constraints during PCB layout. Verify compatibility with the system's voltage rails, as the device supports analog voltages up to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI-300 series of CMOS analog switches from Harris Semiconductor. The series includes various configurations such as quad SPST and dual SPDT switches. The HI30300-5 specifically represents the dual SPST variant. These devices are characterized by their use of proprietary dielectric isolation processes to minimize leakage and crosstalk between channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other HI-300 series variants like the HI30300 or HI30301 if pinout compatibility allows. Cross-reference with Intersil or Renesas equivalents for modern sourcing. Verify that any replacement maintains the 14-DIP package and 50 Ohm resistance specifications.
