HI1-5046A-8

Overview

The HI1-5046A-8 is a dual-channel analog switch manufactured by Harris Corporation, housed in a PDIP-16 package. It features two single-pole single-throw (SPST) switches within a single integrated circuit. The device operates with a nominal on-resistance of 25 ohms and provides a break-before-make switching action to prevent signal shorting. It supports TTL and CMOS logic inputs for versatile control compatibility. The component utilizes dielectric isolation processing to ensure latch-free operation and low leakage currents across the operating temperature range.

Feature Summary

• Dielectric isolation processing ensures latch-free operation and low input/output leakage currents
• Break-before-make switching action prevents signal path shorting during transitions
• TTL and CMOS compatible logic inputs provide broad application versatility
• Low and stable on-resistance remains constant over full operating signal voltage and current ranges

Applications

• Signal routing in data acquisition systems
• Multiplexing applications requiring isolated signal paths
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that original documentation may reference legacy branding. Confirm the PDIP-16 package type and pinout configuration against official datasheets before integration. Check for RoHS compliance status, as older Harris components may not meet current environmental standards. Ensure supply chain authenticity through authorized distributors to avoid counterfeit devices.

Selection Notes

Select this component when dual independent SPST switching is required with low on-resistance stability. Consider the 25-ohm nominal resistance and 75°C maximum operating temperature limits. Verify power supply requirements align with system capabilities, as the device typically requires dual supplies. Evaluate the PDIP-16 footprint constraints against available PCB space.

Part Context

This part belongs to the HI-5040 through HI-5051 family of analog switches from Harris Semiconductor. These devices share common characteristics such as dielectric isolation and CMOS/TTL compatibility. The HI-5046A variant specifically offers dual channels with distinct switching performance compared to single-channel counterparts in the same series.

Replacement Considerations

Compatible substitutes include other HI-5046A variants with different suffixes if pinout and electrical parameters match. Cross-reference with Harris successor product lines for modern equivalents. Verify functional compatibility regarding on-resistance and isolation specifications before substitution.
