The MAX214 +5V RS-232 transceiver provides a complete, 8-line, software-configurable, DTE or DCE port RS-232 interface. Tx, Rx, RTS, CTS, DTR, DSR, DCD, and RI circuits can be configured as either Data Terminal Equipment (DTE) or Data Circuit-Terminating Equipment (DCE) using the DTE/DCE control pin. The MAX214 eliminates the need to swap cables when switching between DTE and DCE configurations.
The MAX214 provides a complete 8‑line RS‑232 interface that can be programmed as either DTE or DCE via a control pin, eliminating the need for separate null‑modem cables. It operates from a single +5 V supply and includes dual charge‑pump converters to generate the required ±10 V levels.
Key features include a guaranteed 116 kbps data rate, shutdown current as low as 4 µA, and configurable HI‑Z inputs for flexible multi‑receiver applications. The device is offered in DIP and SO packages with a wide operating temperature range.
