HI1-0509A/B

Overview

The HI1-0509A/B is a differential 4-channel multiplexer/demultiplexer manufactured by Rochester Electronics. It features a dielectric isolation process to eliminate latch-up and offers low on-resistance of 180 ohms with a wide analog signal range of ±15V. The device supports TTL/CMOS compatible logic inputs, has a maximum access time of 250ns, and operates within a temperature range of -55°C to +125°C. It utilizes break-before-make switching and includes protection against transient overvoltages via internal series resistors and diode clamps.

Feature Summary

Dielectric isolation fabrication eliminates latch-up issues and reduces substrate leakage.
Differential 4-channel architecture provides high-performance signal routing.
Break-before-make switching ensures smooth transitions without signal overlap.
Internal digital input protection guards against transient overvoltage events.

Applications

Harsh environment data acquisition systems
Military aerospace instrumentation
High-reliability industrial control interfaces

Procurement Notes

Verify the specific suffix (A or B) matches the required operating temperature grade and screening level. Confirm MIL-STD-883 qualification status if applicable. Ensure the ordering information aligns with the authorized source documentation provided by the manufacturer to guarantee authenticity and traceability.

Selection Notes

Select this component for applications requiring differential signal handling in harsh environments. The dielectric isolation process makes it suitable where standard CMOS devices might suffer from latch-up. Verify that the ±15V supply capability and 180Ω on-resistance meet the system's analog performance requirements.

Part Context

This part belongs to the HI-506/HI-507/HI-508/HI-509 family of monolithic CMOS multiplexers. The HI1-0509A/B specifically corresponds to the 4-channel differential configuration. It serves as a replacement for legacy parts like the DG509A/DG509AA, maintaining compatibility while offering enhanced reliability through dielectric isolation technology.
