Product details

Half-duplex transceiver for RS422/RS485 buses

The DS36277TMX/NOPB is a half-duplex transceiver from Texas Instruments supporting both RS422 and RS485 protocols. Operating from a 4.75V to 5.25V supply, the device delivers 80 mV of receiver hysteresis for noise immunity on long cable runs.

Package and mounting — 8-SOIC with surface-mount assembly

Mounting is surface-mount, compatible with standard reflow profiles. No exposed pad or thermal vias are required — the package dissipates through the leads and board copper.
