MAX218CAP+

Drivers, Receivers, Transceivers Overview

The MAX218CAP+ is a dual RS-232 transceiver designed for battery-powered EIA/TIA-232E and V.28/V.24 interfaces. It operates from a single supply voltage ranging from +1.8V to +4.25V, enabling direct connection to two alkaline, NiCd, or NiMH cells without external regulators. The device integrates on-board DC-DC converters to generate true RS-232 voltage levels. It features two drivers and two receivers with a guaranteed data rate of 120kbps. A shutdown mode reduces supply current to 1µA, while three-state receiver outputs allow wire-ORing at the UART. The component is housed in a 20-pin SSOP package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and temperature range. The 'CAP' designation indicates a 20-pin SSOP package with an operating temperature range of 0°C to +70°C. Ensure compatibility with required interface standards before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption and operation from unregulated battery sources. It is suitable for systems needing two drivers and two receivers with a maximum data rate of 120kbps. Consider the integrated DC-DC converter requirements when designing the power supply section.

Drivers, Receivers, Transceivers Part Context

The MAX218 is part of the Maxim Integrated RS-232 transceiver family, specifically designed for low-voltage, battery-operated serial communication interfaces. It serves as a cost-effective alternative to bipolar transceivers by eliminating the need for external voltage regulators.
