Overview
The Harris Corporation DG441EJ is a CMOS analog switch IC featuring four single-pole single-throw (SPST) channels. It operates on dual supplies ranging from ±3V to ±18V or a single supply up to 36V. The device offers low on-resistance and fast switching speeds, with typical on-resistance of 25 ohms and channel-to-channel matching of 10 milliohms. Input bias current is typically 1 nanoampere. It is housed in a 16-pin DIP package and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- CMOS technology for low power consumption
- Four independent SPST channels
- Low on-resistance and high bandwidth
- Compatible with TTL and CMOS logic levels
Applications
- Data acquisition systems
- Communication equipment
- Industrial process control
Procurement Notes
Verify the manufacturer origin as Harris Corporation or its successors like Intersil/Renesas. Confirm RoHS compliance status as original Harris parts may not meet modern standards. Check for lead-free plating if required by assembly processes. Ensure the package matches the 16-pin DIP specification.
Selection Notes
Select this component when four isolated analog switches are needed with low distortion. Compare on-resistance stability over voltage and temperature against alternatives. Verify that the input signal range fits within the supply rails. Consider pin compatibility with existing PCB layouts using standard 16-pin DIP footprints.
Part Context
This part belongs to the DG441 series of quad SPST analog switches. It is functionally similar to other CMOS switches but distinguished by its specific on-resistance characteristics and packaging. The DG441EJ variant specifically denotes the epoxy package version.
Replacement Considerations
Consider Vishay DG441DYZA or DG441LDQ-E3 for surface mount equivalents. Analog Devices ADG1611BRUZ offers a modern alternative with improved specifications. Verify pinout compatibility before substitution.
