Overview
The HI1-0508-4 is a fault-protected analog multiplexer manufactured by Intersil, classified under signal circuits. It features eight single-ended channels within a 16-pin DIP package. The device utilizes a Dielectric Isolation (DI) CMOS process to eliminate latchup and reduce substrate leakage. It operates with a nominal negative supply voltage of -15 V and supports a maximum on-resistance of 1500 Ω. The component provides a typical off-isolation of 68 dB and functions across a temperature range from -55 °C to +125 °C.
Feature Summary
- Dielectric isolation process eliminates latchup and reduces parasitic capacitance
- Internal digital input protection against transient overvoltages
- Direct interface capability with standard logic families without pull-up resistors
Applications
- Avionics systems requiring high-reliability signal routing
- Spaceborne data acquisition equipment
- Harsh environment instrumentation
Procurement Notes
Verify the specific suffix '-4' against official Intersil documentation to confirm exact qualification level and screening requirements. Ensure compatibility with MIL-STD-883 standards if required for the application. Confirm that the ceramic DIP package meets thermal and mechanical specifications for the intended operating environment.
Selection Notes
Select this component when fault protection and high channel count are required in a single package. The DI process makes it suitable for environments where latchup is a critical failure mode. Verify that the 1500 Ω on-resistance meets the signal integrity requirements of the specific application circuit.
Part Context
This part belongs to the HI-508 series of monolithic CMOS multiplexers. It shares architectural similarities with the HI-506, HI-507, and HI-509 models but offers an 8-channel configuration. The series is known for its robust design using dielectric isolation technology, distinguishing it from conventional junction-isolated CMOS devices.
Replacement Considerations
The JM38510/19007BEA is identified as the JAN version of the HI1-0508. Verify pinout and electrical parameter equivalence before substitution. Ensure the replacement meets the same environmental and reliability qualifications.
