The SN65HVD21MDREP is a robust 3.3-V RS-485 transceiver from Texas Instruments, designed to meet the demanding requirements of industrial communication networks. Operating over a wide temperature range, this device is part of the TI's "Enhanced Product" (EP) lineup, which ensures it can reliably function in extreme environments, making it ideal for applications such as factory automation, HVAC systems, and energy metering.

Key Features

• Extended Temperature Range: The SN65HVD21MDREP is designed to operate over an industrial temperature range of -55°C to 125°C, ensuring reliable performance in harsh conditions.
• Robust ESD Protection: With an integrated electrostatic discharge (ESD) protection exceeding 15 kV IEC61000-4-2 (air-gap discharge) and 8 kV IEC61000-4-2 (contact discharge), the device is well-suited for environments where ESD events are common.
• Low Power Consumption: The device features a low standby current, making it suitable for power-sensitive applications.
• High Data Rate: It supports data rates up to 20 Mbps, enabling high-speed data transmission for efficient communication.
• Fail-Safe Receiver: The receiver has a fail-safe feature that ensures a logic-high output if the input is open circuit, shorted, or idle (bus idle state).

Applications

• Industrial control and automation
• Building management systems
• Networked security systems
• Remote data acquisition

The SN65HVD21MDREP is housed in an 8-pin SOIC package, which is compact and suitable for space-constrained applications. Its pinout is designed for easy PCB routing, and it is fully interoperable with other 3.3V RS-485 transceivers, ensuring compatibility with existing network components.

With its combination of performance, reliability, and data integrity, the SN65HVD21MDREP from Texas Instruments represents a robust solution for any application requiring high-speed, bidirectional data communication under stringent conditions.
