Overview
The HI4P0509-5 is a multiplexer switch IC from the HI4P0509 series, manufactured by Renesas Electronics (formerly Intersil). It features an 8:1 multiplexing configuration with overvoltage protection and is housed in a 28-pin PLCC package. The device supports single or dual supply voltages, with a maximum operating voltage of 22 V and a maximum dual supply voltage of 18 V. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, a maximum power supply current of 2 mA, and switching times (on and off) of up to 300 ns. It operates within a temperature range of 0°C to +75°C.
Feature Summary
- Integrated overvoltage protection for signal line safeguarding
- High isolation between channels in multiplexed configurations
- Compatible with standard digital control logic levels
Applications
- Data acquisition systems requiring signal routing
- Test and measurement equipment input stages
- Industrial process control signal conditioning
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check for recent product change notifications regarding manufacturing site transfers or material updates. Ensure storage conditions meet specified humidity limits to prevent package degradation before soldering.
Selection Notes
Select this component when an 8-channel multiplexer with integrated overvoltage protection is required. Compare on-resistance and leakage current specifications against system signal integrity needs. Verify that the 28-pin PLCC package fits the PCB layout constraints. Consider the 300 ns switching speed suitability for the target data rate. Evaluate thermal dissipation capabilities within the 0°C to +75°C operating range.
Part Context
This part belongs to the HI4P0509 family of analog multiplexer switches. It shares functional similarities with other devices in the series but differs in channel count and specific pinout configurations. The HI4P0509 series is designed for applications requiring reliable signal switching with built-in protection features. It complements other interface ICs in the portfolio for complete system solutions.
Replacement Considerations
Consult official datasheets for pin-compatible alternatives within the same family. Verify electrical parameter equivalence for on-resistance, leakage, and switching speeds. Check package dimensions and thermal characteristics for mechanical fit. Review manufacturer recommendations for cross-references or updated components.
