MAX214CWI

Drivers, Receivers, Transceivers Overview

The MAX214CWI is a +5V RS-232 transceiver in a 28-pin Wide SO package, rated for an operating temperature range of 0°C to +70°C. It provides eight software-configurable lines (Tx, Rx, RTS, CTS, DTR, DSR, DCD, RI) selectable as Data Terminal Equipment or Data Circuit-Terminating Equipment via the DTE/DCE pin. The device operates from a single +5V supply using dual charge pumps with four 1µF capacitors to generate ±10V levels. It supports data rates up to 116kbps and features a shutdown mode drawing typically 4µA while keeping receivers active.

Drivers, Receivers, Transceivers Feature Summary

• Eliminates the need for null modem cables through software-selectable DTE or DCE port configurations
• Integrates dual charge-pump voltage converters requiring only four 1µF external capacitors
• Maintains receiver activity during shutdown mode for ring indicator detection
• Includes internal pull-up resistors on unused driver inputs to simplify design

Drivers, Receivers, Transceivers Applications

• AT-Compatible Laptop Computers
• AT-Compatible Desktop Computers
• Modems, Printers, and Other Peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'W' indicates the Wide SO package and 'C' denotes the commercial temperature range. Confirm that the component is sourced from Analog Devices Inc./Maxim Integrated channels following the corporate acquisition. Ensure documentation matches the official datasheet specifications for the MAX214 series.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-supply RS-232 interface is required without external negative voltage generation. The MAX214CWI is suitable for applications needing flexible DTE/DCE configuration to avoid cable swapping. Consider the 116kbps data rate limit and the requirement for four 1µF capacitors for the charge pump circuitry.

Drivers, Receivers, Transceivers Part Context

The MAX214 belongs to the Maxim Integrated RS-232 transceiver family, designed for standard serial communication ports. The 'C' variant specifies the commercial temperature range, while the 'W' suffix identifies the 28-pin Wide Small Outline package. This part integrates the necessary voltage conversion and logic level shifting for direct connection to DB-9 or DB-25 connectors.
