HI9P5051-9R2490

Overview

The HI9P5051-9R2490 is a CMOS analog switch belonging to the HI-505X series, designed for harsh environment applications. It features a wide analog signal range of ±15V and low ON resistance of 25Ω. The device supports high current capability up to 80mA and provides break-before-make switching with turn-on time of 370ns and turn-off time of 280ns. Input MOS gates are protected from electrostatic discharge, and it is compatible with DTL, TTL, and CMOS logic levels. The component operates within a temperature range of -55°C to +125°C and utilizes dielectric isolation processing to ensure latch-free operation.

Feature Summary

• Dielectric isolation processing ensures latch-free operation with very low input and output leakage currents
• Break-before-make switching action prevents signal overlap during transitions
• Input MOS gates are protected from electrostatic discharge for enhanced reliability
• Compatible with DTL, TTL, and CMOS logic families for versatile interface integration

Applications

• Harsh environment switching applications requiring MIL-STD-883 qualification
• Analog signal routing in systems demanding low on-resistance stability
• High current signal switching up to 80mA capability
• Replacement for IH-5040 series devices in existing designs

Procurement Notes

Verify that the specific suffix 9R2490 corresponds to the required packaging or qualification level, as standard datasheets may list generic series parameters. Confirm RoHS compliance status if lead-free variants are strictly required for the assembly process. Ensure the supply voltage limits of ±15V align with the system design constraints before procurement.

Selection Notes

Select this component when a CMOS analog switch with low on-resistance (25Ω) and high current handling (80mA) is required. It is suitable for applications needing compatibility with multiple logic families including TTL and CMOS. Consider the operating temperature range of -55°C to +125°C for environments with extreme thermal conditions. Verify that the break-before-make switching characteristic meets the timing requirements of the signal path.

Part Context

This part belongs to the HI-504X and HI-505X series of CMOS analog switches. These devices offer low resistance switching performance for analog voltages up to the supply rails. The series includes seven devices differentiated by switch action type and ON resistance values. The HI-5051 specifically provides 25Ω ON resistance, distinguishing it from other members like the HI-5042 through HI-5047 which have 50Ω ON resistance.

Replacement Considerations

The HI-504X and HI-505X series switches can directly replace IH-5040 series devices. They are functionally compatible with the DG180 and DG190 family. Verify pinout compatibility and electrical specifications against these alternative part numbers before substitution.
