What are the key features of ST232CN?

  • Single 5 V supply, multi-channel RS-232 driver/receiver
  • 2 line drivers with Schmitt-trigger inputs for noise immunity
  • Compliant with EIA-232, TIA-232, and V.28 interface standards
  • Low high-level input current: 0.2 mA maximum
  • 16-pin PDIP through-hole package (JESD-30 R-PDIP-T16)
  • Pb-free construction per JESD-609 code e4

What is ST232CN used for?

This RS-232 line driver/receiver is commonly used in industrial equipment, test instruments, and legacy serial communication ports that require reliable EIA-232 signal conversion from a single 5 V supply. Its Schmitt-trigger inputs and 16-pin PDIP package also make it well suited for retrofit designs replacing older dual-supply RS-232 transceivers.
