Overview
The HI4P5051-5 is a high-speed, single-pole double-throw (SPDT) analog switch manufactured by Harris Corporation. It utilizes CMOS technology to provide low on-resistance and fast switching times for signal routing applications. The device operates with a wide supply voltage range of ±5V to ±15V and supports bidirectional analog signals up to the supply rails. Key electrical parameters include a maximum on-resistance of 25Ω, a typical turn-on time of 370ns, and a typical turn-off time of 280ns. It features break-before-make switching action and is compatible with DTL, TTL, and CMOS logic families.
Feature Summary
- Provides break-before-make switching action to prevent signal shorting during transitions
- Offers dielectric isolation processing to ensure latch-free operation and low leakage currents
- Supports bidirectional analog signal transmission across the full supply voltage range
- Maintains constant on-resistance over temperature variations and signal current levels
Applications
- High-speed data acquisition systems requiring precise signal routing
- Audio and video signal switching matrices
- Instrumentation and test equipment multiplexing
- Communication systems requiring isolated signal paths
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability of refurbished units. Confirm package type and marking codes match original specifications. Check for RoHS compliance status as legacy Harris parts may vary in lead content. Ensure storage conditions meet moisture sensitivity requirements if applicable.
Selection Notes
Select this component when high-speed switching and low distortion are critical. Compare on-resistance stability against alternative CMOS switches for precision applications. Verify supply voltage compatibility with system rails. Consider thermal dissipation requirements given the power consumption characteristics at maximum operating temperatures.
Part Context
This part belongs to the HI-5051 family of CMOS analog switches from Harris Semiconductor. The series includes variants like HI-5051 and HI-5051/883, differentiated by packaging and qualification levels. These devices were designed to replace older bipolar analog switches, offering lower power consumption and higher integration density while maintaining robust performance in harsh environments.
Replacement Considerations
Functionally compatible replacements include the DG180 and DG190 families. The HI-504X series devices offer similar performance characteristics. Verify pinout compatibility before substitution. Check switching speed and on-resistance specifications to ensure equivalent performance in the target application.
