Overview
The HI1-0509-9 is a monolithic CMOS multiplexer manufactured by Harris Corporation, featuring a differential 4-channel configuration. It integrates an array of analog switches with a digital decoder circuit for channel selection and includes an enable input for device selection in multi-device systems. The component utilizes Dielectric Isolation (DI) technology to eliminate latch-up issues and reduce substrate leakage. It operates on dual power supplies ranging from ±10V to ±15V, with a maximum supply voltage of 22V. Key electrical parameters include a maximum transition time of 1.2µs and a positive supply current of 3mA.
Feature Summary
- Dielectric Isolation process eliminates latch-up and reduces parasitic capacitance
- Internal +5V reference establishes switching thresholds for TTL/CMOS compatibility
- Integrated transient overvoltage protection via series resistors and diode clamps
Applications
- Harsh environment data acquisition systems requiring MIL-STD-883 qualification
- Differential signal routing in instrumentation circuits
- Multi-channel sensor interface modules
Procurement Notes
Verify the specific suffix -9 against official datasheets to confirm temperature range and package variations. Confirm RoHS compliance status as older Harris components may not meet modern environmental standards. Check for discontinuance notifications or obsolescence notices from Renesas or Intersil, as this part number belongs to a legacy product line. Ensure availability of qualified sources for military-grade specifications if required.
Selection Notes
Select this component when differential signal integrity is critical and latch-up immunity is required in harsh environments. Compare against the HI-506, HI-507, and HI-508 variants based on channel count and single-ended versus differential requirements. Verify that the ±10V to ±15V supply range matches the system design. Consider the HI-546/HI-547/HI-548/HI-549 series if input overvoltages exceed standard operating limits.
Part Context
The HI1-0509-9 is part of the HI-506/HI-507/HI-508/HI-509 family of monolithic CMOS multiplexers. The HI1-0509 specifically denotes the JAN version of the HI-509, which is a 4-channel differential multiplexer. This family shares common features such as dielectric isolation and TTL/CMOS compatible logic inputs, differing primarily in channel count and signal configuration.
Replacement Considerations
Public confirmed substitutes include the JM38510/19007BEA (JAN version of HI1-0508) for single-ended applications and the JM38510/19008BEA (JAN version of HI1-0509) for differential applications. Commercial equivalents like the DG509A/DG509AA are also listed as replacements in documentation.
