Overview
The DG529CK is a dual-channel analog switch manufactured by Harris Corporation, housed in an 18-pin CERDIP package. It features a single supply voltage range of up to 44V or dual supplies of ±22V. The on-state resistance is typically 450 Ohms with channel-to-channel matching of 27 Ohms. Leakage current is limited to 500pA. Switching times are specified at 250ns for turn-on and 120ns for turn-off. The device operates within a temperature range of -55°C to 125°C.
Feature Summary
- Dual-channel configuration supporting 4:1 multiplexing applications
- Low leakage current specification suitable for precision signal routing
- Robust on-state resistance matching between channels
- CERDIP packaging designed for high-reliability environments
Applications
- Data acquisition systems requiring signal isolation
- Industrial process control instrumentation
- Communication equipment signal routing
- Test and measurement hardware interfaces
Procurement Notes
Verify the specific manufacturer source, as Harris Corporation's semiconductor assets have undergone various acquisitions. Confirm that the 18-CERDIP package matches the required footprint and pin compatibility. Check RoHS compliance status, as older ceramic packages may not meet current environmental standards. Ensure the operating temperature range meets the specific application requirements before finalizing procurement.
Selection Notes
Select this component when dual-channel isolation with low leakage is critical. The 450 Ohm on-resistance is suitable for moderate bandwidth applications. Consider the CERDIP package for superior thermal and mechanical stability compared to plastic variants. Verify supply voltage constraints against the 44V single or ±22V dual limits. Evaluate switching speed requirements against the 250ns/120ns specifications.
Part Context
The DG529CK belongs to Harris Corporation's legacy line of precision analog switches. These devices were widely used in military and aerospace applications due to their ceramic construction and reliability. The part represents a transition period in semiconductor manufacturing where high-performance analog switches were essential for complex signal processing tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with updated manufacturers such as Analog Devices or Texas Instruments for modern equivalents. Verify pinout compatibility and electrical parameter overlaps before considering alternative sources.
