Maxim Integrated MAX232ESE+T RS-232 Interface IC

The MAX232ESE+T from Maxim Integrated is a highly-reliable, dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply. Each receiver converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3V, a typical hysteresis of 0.5V, and can accept ±30V inputs. Each driver converts TTL/CMOS input levels into TIA/EIA-232-F levels.

This device is optimized for enhanced ESD protection and is capable of withstanding ±15kV ESD shocks, making it extremely robust for industrial environments where electrical noise and transient voltages may be problematic. The MAX232ESE+T features a dual charge pump circuitry that allows for operation from a single 5V source, while still delivering true RS-232 performance.

Key features of the MAX232ESE+T include:

• Supply Voltage: Operates from a single 5V supply.
• Data Rate: Up to 120kbps for efficient data transfer.
• Transmitter Output Levels: ±5V to ±10V.
• Receiver Input Levels: ±30V.
• Low Power Shutdown: A low power shutdown mode reduces power consumption when not in use.
• ESD Protection: ±15kV Human Body Model (HBM) ESD protection on transmitter outputs and receiver inputs.
• Package Type: Housed in a Narrow SOIC-16 package for compact footprint.

Designed for applications that require reliable data transmission, the MAX232ESE+T is ideal for use in point-of-sale machines, peripherals, modems, and serial data communication in embedded systems. Its robust ESD protection ensures long-term reliability in harsh environments, making it a preferred choice for industrial and commercial applications.

Maxim Integrated's commitment to quality and performance is evident in the MAX232ESE+T, making it a smart choice for designers looking for a dependable RS-232 interface solution. With its combination of features, this device ensures seamless and secure serial communication for a broad range of electronic applications.
