MAX3188EEUT+T

Product Overview

The MAX3188EEUT+T from Analog Devices Inc./Maxim Integrated is a surface-mount RS232 line driver in a SOT-23-6 package. It is configured as a 1/0 driver, providing one transmit driver channel and no receiver channel. The device operates from a 4.5V to 6V supply and has an operating temperature range of -40°C to 85°C. Its specified data rate is 250kbps. The SOT-23-6 package supports surface-mount assembly, and the part is for interface designs that require a single-channel RS232 transmit path rather than a combined driver and receiver.

Key Features

• RS232 protocol driver with a 1/0 driver/receiver configuration
• Full-duplex protocol designation with a specified data rate of 250kbps
• Supply voltage range of 4.5V to 6V
• Operating temperature range of -40°C to 85°C
• Surface-mount SOT-23-6 package
• Receiver hysteresis specified as 100 mV

Applications

• Transmitting RS232 serial data from a controller or host interface to a receiving device
• Supplying the transmit channel of a full-duplex RS232 link when receiver functions are implemented separately
• Providing a surface-mount RS232 output stage in equipment that uses a 4.5V to 6V interface supply

Design & Procurement Notes

Designers should verify that the target system requires a transmit-only RS232 path, because the device provides one driver and no receiver. The 4.5V to 6V supply range and -40°C to 85°C operating temperature range should be checked against the board power and environmental conditions. The specified data rate of 250kbps should be matched to the intended serial link. The SOT-23-6 surface-mount package affects land pattern, stencil, and reflow considerations. The 100 mV receiver hysteresis specification can be considered when receive-side behavior is relevant to the interface design, while transmit-only implementations should focus on driver output requirements. Procurement should reference the exact part number MAX3188EEUT+T to preserve the specified package and electrical configuration.
