Overview
The MAX3232EID is a dual driver and receiver RS-232 transceiver manufactured by Texas Instruments. It operates from a single 3V to 5.5V supply, utilizing an internal dual charge pump to generate the required ±9V levels for RS-232 signaling without external negative voltage sources. The device supports data rates up to 250 kbit/s with a maximum slew rate of 30 V/μs. It features ±15kV IEC ESD protection on all serial-port connection pins, including ground. The component is housed in a 16-pin SOIC-Wide (DW) package.
Feature Summary
- Dual drivers and receivers provide full-duplex communication capability
- Integrated dual charge pump enables operation from a single power supply
- Serial port pins include ±15kV IEC electrostatic discharge protection
Applications
- Industrial PCs
- Wired networking equipment
- Data center and enterprise computing systems
Procurement Notes
Verify the specific suffix 'ID' against the manufacturer's current orderable part list to confirm availability and exact packaging specifications. Confirm that the industrial temperature range (-40°C to +85°C) aligns with the target application environment requirements before finalizing procurement.
Selection Notes
Select this component when a standard RS-232 interface is required for microcontroller or UART connections. Ensure the design accommodates four external capacitors for the charge pump circuit. Verify that the 250 kbit/s data rate meets the system's throughput needs, as higher-speed alternatives exist within the same family.
Part Context
This device belongs to the MAX3232 series of multichannel RS-232 line drivers and receivers. It serves as a bridge between asynchronous communication controllers and serial-port connectors, providing the necessary electrical interface for reliable data transmission in standard RS-232 environments.
Replacement Considerations
The SNx5C3232 series is identified as a pin-compatible alternative offering higher data rates up to 1 Mbit/s. Verify pinout compatibility and electrical characteristics before substituting.
