That supply range makes it a direct fit for 3.3V-only or Li-ion battery-powered boards where a 5V rail isn't available. The 2/2 driver/receiver count covers a basic UART handshake pair (TX/RX plus CTS/RTS) without needing an external level shifter. Full-duplex operation means the transmit and receive paths run simultaneously — no half-duplex turnaround delay. The 460 kbps data rate handles most legacy RS-232 peripherals (terminals, barcode scanners, serial printers) but falls short of the 1 Mbps some industrial Modbus or Profibus implementations require. ## Active lifecycle and sourcing posture ROHS3 compliant. For BOM planning, the 20-TSSOP package is a common footprint shared by several TI RS-232 transceivers. If allocation pressure hits, a pin-compatible sibling in the same package family is a viable second-source route — confirm the supply voltage and data rate match your design.","metaTitle":"MAX3318ECPW RS-232 Transceiver 2/2 Full Duplex 460Kbps","metaDescription":"Texas Instruments MAX3318ECPW RS-232 transceiver, 2/2 drivers/receivers, full duplex, 460Kbps data rate, 2.25V–3V supply, 20-TSSOP.
