MAX240CMH+

Overview

The MAX240CMH+ is a full RS-232 transceiver featuring five drivers and five receivers in a 44-MQFP package. It operates on a single +5V supply, utilizing an integrated charge pump to generate the required ±10V internal voltages without external bipolar supplies. The device supports data rates up to 120Kbps with a receiver hysteresis of 500mV. It functions within a commercial temperature range of 0°C to +70°C and requires a supply voltage between 4.5V and 5.5V.

Feature Summary

Integrates dual charge-pump DC-DC converters to eliminate the need for external bipolar power supplies
Provides five independent drivers and five independent receivers for full duplex communication
Includes shutdown control inputs to minimize power consumption during idle periods

Applications

Interface translation between TTL/CMOS logic and RS-232 serial ports
Multidrop RS-232 network connections
Portable diagnostic equipment requiring low-power serial communication

Procurement Notes

Verify the component status as obsolete based on distributor records. Confirm that the specific ordering suffix matches the required package type and temperature grade. Ensure compliance with RoHS3 standards before procurement. Check for valid datasheet revisions to confirm electrical characteristics match design requirements.

Selection Notes

Select this component when a high channel count (5/5) is required in a compact surface-mount form factor. Verify that the system operates within the specified +5V supply range and does not require extended industrial temperatures. Consider the 44-pin footprint constraints during PCB layout planning.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The family offers various configurations of driver and receiver counts across multiple package types. The MAX240 specifically provides the highest channel density within this series.
