Overview
The MAX243EPE+ is a dual-driver, dual-receiver RS-232 transceiver from the MAX220–MAX249 family. It operates on a single +5V supply using an integrated charge pump to generate ±10V internally. The device supports data rates up to 200kbps with typical propagation delays of 3.5µs for drivers and 1µs for receivers. It features TTL/CMOS-compatible inputs and outputs, ±30V receiver input protection, and continuous short-circuit protection on driver outputs. The component is housed in a 16-pin PDIP package.
Feature Summary
- Integrated charge pump eliminates external bipolar power supplies
- Single +5V operation capability
- TTL and CMOS logic compatibility
- Built-in receiver and transmitter enable controls
Applications
- Interface translation between TTL/CMOS and RS-232 standards
- Multidrop RS-232 network connections
- Portable diagnostic equipment requiring low power consumption
Procurement Notes
Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range. Confirm the 'P' indicates the 16-pin plastic DIP package. Ensure the '+' suffix denotes lead-free compliance. Cross-reference the manufacturer's current production status as availability may vary.
Selection Notes
Select this part when a single +5V supply is available but RS-232 voltage levels are required. It is suitable for applications needing two independent transmit and receive channels. Consider the MAX243CWE+ variant if surface-mount packaging is preferred over through-hole DIP.
Part Context
This component belongs to the Maxim Integrated MAX220–MAX249 series of +5V-powered multichannel RS-232 drivers and receivers. The series provides various channel configurations and package options designed to simplify serial communication interface design without requiring complex external power generation circuits.
Replacement Considerations
The MAX243CWE+ serves as a direct functional equivalent in a surface-mount SOIC package. Other members of the MAX220–MAX249 family offer similar core functionality with varying channel counts or control pin configurations.
