HI1-0303-5

Overview

The HI1-0303-5 is a monolithic CMOS analog switch fabricated using dielectric isolation technology. It features break-before-make switching, low and nearly constant ON resistance over the full analog signal range, and low power dissipation. The device is TTL compatible with defined logic thresholds. It operates within a temperature range of -55°C to +125°C. Key electrical parameters include a maximum RON of 35 ohms, a turn-on time of 300 ns, and a turn-off time of 250 ns. Supply voltage ranges from -15V to +15V.

Feature Summary

• Monolithic CMOS construction with dielectric isolation for robust performance
• Break-before-make switching action prevents signal shorting during transitions
• Low and stable ON resistance across the entire analog signal range
• TTL logic compatibility simplifies interface with digital control circuits

Applications

• Sample and hold circuits requiring low leakage switching
• Op amp gain switching applications demanding low on-resistance
• Portable and battery-operated circuits due to low power dissipation
• Low level switching circuits in dual or single supply systems

Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct channels. Confirm package type matches CERDIP specifications and lead count is 14. Check for RoHS compliance status as original versions may not be lead-free. Validate temperature grade corresponds to industrial standards if operating in extreme environments. Request datasheet revision history to ensure design alignment with current manufacturing processes.

Selection Notes

Select this component when break-before-make timing is critical to prevent signal overlap. Ensure supply voltages remain within the ±15V limit to avoid damage. Consider the 35-ohm ON resistance for signal integrity requirements in precision analog paths. Verify TTL input compatibility with the controlling microcontroller or logic family. Evaluate thermal management needs given the wide operating temperature range capability.

Part Context

The HI1-0303 series belongs to Renesas' legacy CMOS analog switch portfolio. These devices are designed for general-purpose signal routing in mixed-signal systems. The HI1-0303-5 variant specifically denotes the commercial/industrial temperature grade version. It complements other switches in the family by offering balanced performance between speed and power consumption.

Replacement Considerations

Direct pin-compatible replacements should be verified against the official Renesas cross-reference guide. Alternative CMOS analog switches must match the 14-pin CERDIP package and ±15V supply capability. Ensure substitute parts maintain similar RON and switching time specifications for circuit compatibility.
