MAX13430EETB+T

Product Overview

The MAX13430EETB+T from Analog Devices Inc./Maxim Integrated is a 1/1 transceiver for RS422 and RS485 serial interfaces. The device uses a half-duplex arrangement, with one driver and one receiver, and supports a data rate of 500 kbps. It operates from a 3 V to 5.5 V supply and is specified for an operating temperature range of -40°C to 85°C. The 10-TDFN (3x3) package, also described as 10-WFDFN Exposed Pad, is surface mount, and the receiver includes 15 mV hysteresis for input signal handling.

Key Features

• 500 kbps data rate
• 3 V to 5.5 V supply range
• 15 mV receiver hysteresis
• -40°C to 85°C operating temperature range
• 10-TDFN (3x3) surface-mount package with exposed pad

Applications

• Serial communication links between embedded controllers and peripheral devices
• Half-duplex data exchange over RS422 or RS485 wiring
• Equipment using a 3 V to 5.5 V supply for 500 kbps serial signaling
• Compact surface-mount interface boards with a 10-TDFN (3x3) transceiver footprint

Design & Procurement Notes

Design considerations should account for the 3 V to 5.5 V supply range, 500 kbps data rate, and half-duplex 1/1 driver/receiver configuration. The 15 mV receiver hysteresis can be useful when evaluating input signal quality, while the -40°C to 85°C operating temperature range should be checked against the intended environment. Board layout should accommodate the 10-TDFN (3x3) surface-mount package and its exposed pad, and procurement planning should align the package and supply voltage with the system interface requirements.
