SN65LBC182DR Description

Short technical summary and product information.

The SN65LBC182DR is a differential data line transceiver from Texas Instruments, designed for balanced transmission lines and meeting ANSI standard TIA/EIA-485-A and ISO 8482. This half-duplex transceiver features one transmitter and one receiver, supporting signaling rates up to 250kbps.

 

Key electrical specifications include a common-mode voltage range of -7V to 12V and receiver hysteresis of 70mV typical. It offers ±8000V ESD protection per IEC 61000-4-2 contact discharge and fault protection from -10V to 15V. The device operates within a temperature range of -40°C to 85°C and requires a supply voltage between 4.75V and 5.25V.

 

Packaged in an 8-SOIC surface-mount configuration, the SN65LBC182DR is suitable for applications requiring robust communication over differential lines. It allows for up to 128 devices on a bus due to its one-fourth unit load capability. Features like controlled driver output-voltage slew rates enable longer cable stub lengths, and thermal shutdown protection is included for added reliability.
