THVD1550DR Description

Short technical summary and product information.

The THVD1550DR from Texas Instruments is a 5-V RS-485 transceiver designed for reliable data transmission in demanding environments. It operates at signaling rates up to 50 Mbps and supports half-duplex communication.

 

Key electrical specifications include a wide supply voltage range of 4.5 V to 5.5 V and a common-mode range of ±15 V. The device offers significant protection against electrostatic discharge, with ±18 kV IEC ESD protection (contact discharge), ±30 kV HBM ESD protection, and ±25 kV IEC ESD protection (air-gap discharge). It also includes ±4 kV EFT protection.

 

This transceiver is suitable for applications requiring extended temperature operation, with a range of -40°C to 125°C. It supports up to 196 nodes on the bus and features receiver hysteresis for improved noise rejection. The device is available in an 8-SOIC package, suitable for surface mounting.

 

The THVD1550DR meets or exceeds the requirements of the TIA/EIA-485A standard. It offers features such as glitch-free power-up/down for hot-plug capability and failsafe protection for open, short, and idle bus conditions.
