Application Scenarios & Design Considerations

7 V, digital line interface controller (DLIC)

Alternative Part Number

  • LM393N --: Dual comparator in DIP-8 with similar open-collector output and wide supply range, a common drop-in substitute for the TP3122J comparator function.
  • LM2903N --: Dual differential comparator with comparable input offset and supply voltage ratings, widely available and pin-compatible with the original device.
  • MC3302P --: Quad comparator offering similar electrical characteristics and DIP package, suitable when a higher channel count replacement is acceptable.
