SN65HVD22DR Description

Short technical summary and product information.

The Texas Instruments SN65HVD22DR is an integrated circuit designed for bidirectional data transmission on multipoint twisted-pair cables, supporting RS-485 and RS-422 protocols. This half-duplex transceiver operates with a supply voltage range of 4.5V to 5.5V and offers a signaling rate of up to 500kbps.

 

Key electrical features include a common-mode voltage range of -20V to 25V, fault protection from -27V to 27V, and 130mV of receiver hysteresis. It supports up to 256 nodes on a bus and includes failsafe receiver operation for open-circuit, short-circuit, and idle-bus conditions. The device also boasts bus I/O protection to over 16-kV HBM.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount configuration, the SN65HVD22DR is rated for an operating temperature range of -40°C to 85°C. Its extended common-mode range and robust protection features make it suitable for harsh environments and long-cable networks, finding applications in areas like industrial process control and remote sensor systems.
