YINGHUA ADM242ARZ RS-232 interface IC SOIC-18

SKU CH-4TGZ-5NQSW

An RS-232 interface integrated circuit in an 18-pin SOIC package

  • Product typeICs Semicoductors
  • RS-232 serial connectivity via ADM242ARZ interface IC
  • Compact SOIC-18 surface-mount package saves board space
  • Single-chip line driver/receiver simplifies circuit design
  • New old-stock component ready for production use

RS-232 interface IC SOIC-18

The YINGHUA ADM242ARZ is an RS-232 interface integrated circuit housed in an 18-pin SOIC package. It provides level translation for serial communication between logic devices and RS-232 bus lines. The component is supplied new and suits engineers adding or repairing serial ports on embedded boards.

Drop-in replacement for legacy 242 series

This IC replaces older 242-series line drivers when the same 18-pin SOIC footprint and RS-232 voltage levels are required. The jump is worth it when a design must maintain pin compatibility while sourcing a currently manufactured device. Buyers needing different pin counts, logic-voltage families or multi-protocol transceivers should look elsewhere.

Questions about this item

What footprint does the SOIC-18 package of the ADM242ARZ require on the PCB?

The ADM242ARZ uses an 18-pin small-outline IC package that mounts on a matching SOIC-18 land pattern.

Which pins carry the RS-232 signals during installation of the ADM242ARZ?

The driver and receiver pins for the 232 interface are defined in the ADM242ARZ datasheet; follow that pin-out when soldering the 18-pin package.
