MAX243ESE

Overview

The MAX243ESE is a +5V-powered, multichannel RS-232 driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within the MAX220–MAX249 family and supports EIA/TIA-232E and V.28/V.24 communication interfaces. The device features two drivers and two receivers with a data rate of 200 kbps. It utilizes an integrated charge pump to generate internal ±10V rails from a single +5V supply, eliminating the need for external bipolar power sources. The component is housed in a 16-pin Wide SO package and functions across a temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external components or bipolar ±12V supplies.
• Enables single-supply operation using only a +5V voltage source.
• Provides full RS-232 signal compatibility for standard serial communication protocols.

Applications

• Interface translation between TTL/CMOS logic levels and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostics equipment requiring low-power serial communication

Procurement Notes

Verify the specific suffix 'ESE' against current manufacturer documentation to confirm the exact package type and operating temperature range. Confirm RoHS compliance status through official datasheets as manufacturing processes may evolve. Ensure that any ordering suffixes do not alter the functional specifications unless explicitly stated in the product literature.

Selection Notes

Select this component when designing systems that require RS-232 connectivity but are constrained to a single +5V power rail. The integrated charge pump reduces board space requirements compared to solutions needing external voltage inverters. Verify that the 200 kbps data rate meets the application's throughput needs and that the 16-pin Wide SO footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers and receivers designed for serial communications.
