SN65C3223DBRG4 Equivalent & Substitute Parts

Part Overview

The SN65C3223DBRG4 is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments in a 20-SSOP surface mount package. This interface IC is designed for serial communication applications requiring RS232 protocol compliance with supply voltage operation between 3V and 5.5V. The SN65C3223DBRG4 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Equivalent alternatives maintain identical electrical specifications and mechanical compatibility while offering active product status or improved availability.
