MAX209CWG+T

Drivers, Receivers, Transceivers Overview

The MAX209CWG+T is a +5V RS-232 transceiver from the Analog Devices/MAXIM family, designed for single-supply operation. It features two drivers and three receivers with an integrated charge pump that generates ±10V internal supplies using only four external 0.1µF capacitors. The device operates on a VCC supply of +5V and requires an external V+ supply ranging from +9.0V to +13.2V. It supports data rates exceeding 120kbps while maintaining EIA/TIA-232E output levels. The component is housed in a 24-pin Wide SOIC package and functions within a commercial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies, enabling single-supply operation.
• Requires only four external 0.1µF capacitors for voltage conversion, significantly reducing board space.
• Drivers maintain specified ±5V EIA/TIA-232E output signal levels at high data rates under standard loading conditions.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Handheld communication devices
• Portable diagnostic instruments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the V+ supply rail is correctly configured between +9.0V and +13.2V, as this variant differs from standard +5V-only models. Confirm RoHS compliance status through the current datasheet revision before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX209CWG+T when the system design provides a secondary positive voltage rail between +9V and +13.2V alongside the primary +5V logic supply. This model is distinct from variants like the MAX206 which operate solely on +5V. Verify that the application requires exactly two drivers and three receivers to match the pinout configuration.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX200–MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. These devices share common architecture including integrated charge pumps and TTL/CMOS compatible inputs. The MAX209 specifically utilizes a dual-supply approach for its charge pump, distinguishing it from other family members that rely exclusively on a single +5V input for voltage generation.
