Overview
The HI1-0305-2 is a CMOS analog switch manufactured by Harris Corporation, designed for precision signal routing in harsh environments. It features two independent switches within a single package, offering a maximum on-resistance of 35 ohms and supporting dual supply voltages ranging from -15V to +15V. The device operates reliably across an extended temperature range of -55°C to +125°C and complies with MIL-STD-883 standards. Key electrical characteristics include a turn-on time of 300 nanoseconds and a turn-off time of 250 nanoseconds, ensuring fast switching performance suitable for demanding industrial applications.
Feature Summary
- Provides dual-channel switching capability within a compact integrated circuit package
- Capable of handling wide analog signal ranges up to the full supply voltage rails
- Engineered for low leakage current operation to maintain signal integrity
- Constructed with dielectric isolation processing to prevent latch-up conditions
Applications
- Sample and hold circuits requiring low leakage switching
- Operational amplifier gain switching applications
- Low-level signal switching in portable battery-operated systems
- Dual or single supply system signal routing
Procurement Notes
Verify the specific manufacturer source and lot traceability before procurement, as this component may be sourced from legacy inventories or authorized distributors. Confirm compliance with relevant environmental regulations and ensure the packaging matches the required DIP specifications for your assembly process. Request detailed datasheets to validate pin configurations and absolute maximum ratings against your design requirements.
Selection Notes
Select the HI1-0305-2 when dual-channel analog switching with low on-resistance is required in high-reliability environments. Consider its compatibility with standard logic families and its ability to handle signals near the supply rails. Evaluate the thermal management needs given the operating temperature range and power dissipation characteristics to ensure stable performance under varying load conditions.
Part Context
This component belongs to the HI-50xx series of CMOS analog switches produced by Harris Corporation, now part of Renesas Electronics. The series is known for its robustness in harsh environments and compliance with military standards. The HI1-0305-2 specifically offers a balance of speed and low resistance, making it a reliable choice for critical signal path applications where reliability is paramount.
Replacement Considerations
The HI-504X and HI-505X series devices can directly replace IH-5040 series components. Functionally compatible alternatives include the DG180 and DG190 family members. Verify pinout compatibility and electrical parameters such as on-resistance and supply voltage limits before substituting.
