Overview
The HI4P0549-5 is a dual-channel analog multiplexer switch IC from the HI-549 series, manufactured by Intersil. It features a 2 x 4:1 configuration, allowing two independent channels to select one of four inputs each. The device supports dual supply voltages ranging from 15 V to 15 V and operates with a single supply voltage of 12 V. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, a maximum turn-on time of 300 ns, and a maximum turn-off time of 300 ns. It functions within an industrial temperature range of -40 C to +85 C and draws a maximum supply current of 2 mA.
Feature Summary
- Dual-channel architecture providing two independent 4-to-1 multiplexing paths for signal routing applications.
- Integrated overvoltage protection (OVP) capabilities to safeguard internal circuitry against input signal excursions beyond specified limits.
- Industrial-grade operational capability ensuring reliable performance across extended temperature environments.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Instrumentation front-ends for sensor signal routing.
- Communication equipment utilizing differential signal switching.
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels due to potential availability constraints. Confirm specific ordering suffixes match required package and temperature grades. Review datasheet revisions for any updates to mechanical dimensions or electrical characteristics prior to final design integration.
Selection Notes
Select this component when dual independent 4:1 multiplexing is required with moderate speed and high impedance isolation. Ensure supply voltage requirements align with the specified 12 V single or +/- 15 V dual rail configurations. Consider the 1.8 kOhm on-resistance limit for signal integrity in high-impedance source applications.
Part Context
This part belongs to the HI-549 family of analog switches, designed for precision signal routing. It complements other variants in the series that may offer different channel counts or pin configurations. The HI4P0549-5 specifically addresses designs needing two separate multiplexing functions within a compact SOIC-Narrow-16 package.
Replacement Considerations
Consult official substitution guides for compatible parts within the HI-549 family or equivalent offerings from Renesas. Verify pin compatibility and electrical parameter equivalence before replacing existing inventory.
