Overview
The HI1-5045-7 is a dual-channel analog switch manufactured by Harris Corporation. It features two independent Double-Pole Single-Throw (DPST) circuits, each providing a 1:1 signal path. The component is designed for applications requiring precise impedance matching, characterized by a nominal on-state resistance of 75 Ohms. It is housed in a 16-pin Ceramic Dual In-Line Package (CERDIP), suitable for high-reliability environments. This integrated circuit functions as a bidirectional switch for analog signals, offering low distortion and fast switching capabilities within its operational specifications.
Feature Summary
- Dual independent DPST analog switching channels
- 75 Ohm nominal on-state resistance for impedance matching
- 16-pin CERDIP package for enhanced reliability
- Bidirectional signal transmission capability
Applications
- Video signal routing and switching systems
- Impedance-matched RF signal paths
- Test and measurement equipment signal conditioning
- High-reliability aerospace communication interfaces
Procurement Notes
Verify the specific suffix '7' to confirm the 16-CERDIP ceramic package variant, as other suffixes may indicate different packaging or performance grades. Confirm RoHS compliance status with the supplier, as legacy Harris components may vary in environmental certification. Ensure the source is an authorized distributor or certified surplus provider to guarantee device authenticity and traceability for critical applications.
Selection Notes
Select this component when a dual-channel switch with 75 Ohm impedance matching is required. The CERDIP package is preferred over plastic DIP for superior thermal stability and hermetic sealing in harsh environments. Consider the on-resistance tolerance and leakage current specifications against the system's signal integrity requirements before finalizing the design integration.
Part Context
This part belongs to the HI1-5045 series of analog switches from Harris Corporation. The series includes variants with different channel counts and resistances, such as the HI1-5044 and HI1-5046. The HI1-5045-7 specifically denotes the dual DPST configuration with 75 Ohm resistance in a ceramic package, distinguishing it from single-channel or lower-resistance alternatives in the same family.
Replacement Considerations
Direct substitutes include the HI1-5045-8 if a compatible pinout and package are verified. Cross-reference with other 75 Ohm dual-channel analog switches from manufacturers like Analog Devices or Maxim Integrated, ensuring identical pin configurations and electrical characteristics to maintain system compatibility without redesign.
