MAX13432EESD+T

Product Overview

The MAX13432EESD+T from Analog Devices Inc./Maxim Integrated is a 1/1 full-duplex transceiver for RS422 and RS485 serial interfaces. It supports a data rate of 500 kbps and operates from a 3 V to 5.5 V supply. The device is housed in a 14-SOIC surface-mount package with a 0.154 inch, 3.90 mm width. Its operating temperature range is -40°C to 85°C, and the receiver input hysteresis is 15 mV. This component is suited to differential serial communication links where one driver and one receiver channel are needed, and where the host supply voltage and board layout are compatible with the SOIC form factor.

Key Features

• 1/1 full-duplex transceiver supporting RS422 and RS485 protocols
• 500 kbps data rate
• 3 V to 5.5 V supply voltage range
• 15 mV receiver hysteresis
• 14-SOIC surface-mount package, 0.154 inch, 3.90 mm width
• Operating temperature range of -40°C to 85°C

Applications

• RS422 differential serial data links between controllers and remote peripherals
• RS485 full-duplex serial communication links with separate transmit and receive channels
• Differential signaling in embedded systems using 3 V to 5.5 V supply rails
• Serial interface segments requiring 500 kbps or lower data throughput

Design & Procurement Notes

When selecting this transceiver, confirm that the interface requires one driver and one receiver in a full-duplex RS422 or RS485 link rather than a half-duplex or multi-channel arrangement. The 500 kbps data rate should be compared with the required serial throughput. The supply rail must remain within 3 V to 5.5 V, and the PCB land pattern should match the 14-SOIC package, including the 0.154 inch, 3.90 mm body width. The -40°C to 85°C operating range is relevant to thermal budgeting, while the 15 mV receiver hysteresis can be considered when evaluating noise margin and signal integrity on differential serial lines.
