THVD1451D Description

Short technical summary and product information.

The THVD1451D from Texas Instruments is a robust RS-485 transceiver IC supporting full-duplex communication. It is engineered to operate across a wide supply voltage range of 3V to 5.5V, making it versatile for various applications.

 

This transceiver boasts a maximum signaling rate of 50Mbps, ensuring efficient data transfer. It features significant ESD protection, including ±18kV IEC 61000-4-2 contact discharge, ±30kV HBM, and ±25kV IEC 61000-4-2 air-gap discharge, enhancing its durability in harsh environments. The device also offers an extended common-mode range of ±15V and operates reliably within an ambient temperature range of -40°C to 125°C.

 

Designed for surface mounting, the THVD1451D comes in an 8-SOIC package. It includes features like receiver hysteresis for improved noise rejection and failsafe operation for open, short, and idle bus conditions. The low power consumption, with standby current less than 1µA and operating current less than 3mA, contributes to energy efficiency in system designs.
