HI3-0547-5Z

Overview

The HI3-0547-5Z is an obsolete analog multiplexer switch IC manufactured by Renesas Electronics Corporation. It features a single circuit configured as an 8:1 multiplexer with a maximum on-resistance of 1.8 kOhms. The device operates within a dual supply voltage range of ±15V and supports a maximum dual supply voltage of 18V. Switching times are specified at a maximum of 300ns for both turn-on and turn-off durations. It is housed in a 16-pin Dual In-line Package (DIP) with a width of 0.300 inches (7.62mm). The component is rated for operation between 0°C and +75°C ambient temperature.

Feature Summary

• Provides 8-to-1 signal routing capability through a single integrated circuit channel.
• Features high off-isolation characteristics to minimize signal leakage when the switch is inactive.
• Designed for dual power supply operation to accommodate bipolar signal ranges.

Applications

• Data acquisition systems requiring multi-channel signal selection.
• Test and measurement equipment utilizing analog signal routing.
• Industrial control circuits managing multiple sensor inputs.

Procurement Notes

This component has been officially discontinued and is no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer orders. Buyers must confirm the authenticity of the source and inspect the physical condition of the units, as these are end-of-life products that may have been stored for extended periods. Compliance with current environmental regulations should be verified against specific batch documentation.

Selection Notes

Designers replacing this part should evaluate modern equivalents from Renesas or other manufacturers that offer similar 8:1 multiplexing functionality. Key parameters to match include the 1.8 kOhm on-resistance, ±15V supply capability, and 16-pin DIP package compatibility. New designs should consider updated components with lower on-resistance and improved switching speeds if performance requirements allow. Ensure that any substitute maintains the necessary isolation levels and operating temperature range for the intended application environment.

Part Context

The HI3-0547-5Z belongs to the HI-547 series of analog multiplexer switches produced by Intersil, now part of Renesas Electronics. This series was widely used in applications requiring reliable analog signal switching. The device represents a legacy solution for systems designed before the industry shift toward higher integration and lower power consumption. Its discontinuation reflects the natural lifecycle of specialized analog interface components as technology evolves.

Replacement Considerations

Publicly confirmed substitutes include the HI4P0547-5Z and HI9P0547-9Z, which share similar functional specifications but differ in package type and channel configuration. The HI3-0548-5Z is also listed as an obsolete alternative within the same family. Designers should verify pinout compatibility and electrical characteristics carefully when selecting these replacements.
