MAX234C/D

Overview

The MAX234C/D is a +5V-powered, multichannel RS-232 line driver/receiver from the MAX220–MAX249 family. It provides four drivers and five receivers for EIA/TIA-232E and V.28/V.24 interfaces without requiring external ±12V supplies. The device operates on a single +5V supply using integrated charge-pump circuitry to generate internal voltages. It supports data rates up to 120kbps with a typical transition slew rate of 8.5V/µs. Operating temperature ranges are 0°C to +70°C for the C suffix and -40°C to +85°C for the D suffix.

Feature Summary

Integrated dual charge-pump DC-DC voltage converters eliminate the need for external bipolar power supplies.
Multichannel architecture includes four independent drivers and five independent receivers.
Supports standard EIA/TIA-232E and V.28/V.24 communication protocols.

Applications

Interface translation between TTL/CMOS logic and RS-232 serial ports
Multidrop RS-232 network connections
Portable diagnostics equipment

Procurement Notes

Verify the specific package type and temperature grade required for your design. The 'C' suffix indicates commercial operation (0°C to +70°C), while the 'D' suffix denotes extended industrial range (-40°C to +85°C). Confirm pinout compatibility if replacing legacy components from this family.

Selection Notes

Select the MAX234C/D when four drivers and five receivers are needed in a single package. Ensure the application does not exceed the 120kbps data rate limit. Verify that the board layout accommodates the necessary external capacitors for the charge pump, as these devices do not have integrated capacitors unlike the MAX233 or MAX235 variants.

Part Context

This component belongs to the Maxim Integrated MAX220–MAX249 family of +5V-powered RS-232 transceivers. This series is designed for applications where space is critical and generating high-voltage RS-232 levels from a single low-voltage supply is required.

Replacement Considerations

The MAX234CPE is a lead-free equivalent of the MAX234C. For designs requiring fewer channels, the MAX232 (2 drivers/2 receivers) or MAX233 (integrated capacitors) may be suitable alternatives within the same family.
