HI1-5045-5

Overview

The HI1-5045-5 is a dual-channel, double-pole single-throw (DPST) analog switch manufactured by Harris Corporation. It utilizes CMOS technology and is housed in a 16-pin ceramic dual in-line package (CDIP). The device operates with a nominal negative supply voltage of -15 V. Key electrical specifications include a maximum on-resistance (Ron) of 75 Ω and an on-resistance matching specification of 2 Ω. The component provides a nominal off-isolation of 80 dB. It is designed for operation within a temperature range extending up to 75 °C.

Feature Summary

• Dual-channel DPST configuration for independent signal routing
• Dielectric isolation processing ensures latch-free operation
• Compatible with TTL and CMOS logic control levels
• Break-before-make switching action prevents signal shorting

Applications

• Signal routing in multiplexed data acquisition systems
• Isolation of sensitive analog measurement channels
• Test and measurement equipment signal paths
• Harsh environment applications requiring ceramic packaging

Procurement Notes

Verify the manufacturer origin carefully, as the HI1-5045 part family was originally developed by Harris Corporation and later acquired by Intersil, which subsequently merged into Renesas Electronics. Confirm whether the specific unit is an original Harris production or a subsequent Renesas/Intersil release. Check for lead-free compliance status, as original Harris versions may not meet current RoHS standards. Ensure the CDIP16 package type matches the target socket or PCB footprint requirements.

Selection Notes

Select this component when dual isolated signal paths are required in a single package. The 75 Ω maximum on-resistance is higher than some modern switches, so verify that the associated circuitry can tolerate the resulting voltage drop at the expected signal current levels. The CDIP package is suitable for through-hole mounting in high-reliability or military-grade designs where plastic packages might be unsuitable. Compare the 80 dB off-isolation against system noise floor requirements.

Part Context

The HI1-5045-5 belongs to the HI-5040 through HI-5051 series of CMOS analog switches. This family shares common characteristics such as dielectric isolation and low charge injection. The 'HI1' prefix typically denotes the dual-channel variant within this broader lineup. These devices were widely used in industrial and aerospace applications before being succeeded by newer generations with lower on-resistance and smaller footprints.

Replacement Considerations

Direct pin-compatible replacements from the same family include the HI1-5045-1 or HI1-5045-2, which may differ only in temperature grade or testing standards. For functional equivalents with different packages, consider the HI1-5045 in SOIC or PLCC formats if available. Cross-reference with Intersil or Renesas datasheets for updated mechanical drawings.
