Procurement Notes
Verify the manufacturer origin carefully as the component was produced by National Semiconductor before its acquisition by Texas Instruments. Ensure the specific suffix matches your board requirements. Confirm the package type is PDIP-14. Check for any military or enhanced variants if high reliability is required. Cross-reference with current TI documentation for updated handling guidelines.
Selection Notes
Select this component when a dual differential line receiver is needed for legacy or specific interface designs. Consider the bipolar technology constraints regarding power consumption and speed. Evaluate the DIP-14 package availability against surface mount alternatives if space is limited. Verify compatibility with existing logic levels and termination requirements.
Part Context
This component belongs to the family of line receivers developed by National Semiconductor. It serves as a critical interface element in serial communication systems. The transition to Texas Instruments has maintained the design specifications while updating manufacturing processes. It remains a recognized solution for robust differential signal reception in established electronic architectures.
Replacement Considerations
The DM8820 is a documented equivalent variant from the same manufacturer. Other dual line receivers in the DIP-14 package may serve as functional substitutes if pin compatibility and electrical specifications align. Always verify datasheet parameters before substitution.
