10 Mbps half-duplex RS-485 in a through-hole DIP
The 30 mV of receiver hysteresis provides built-in noise margin on long cable runs without external fail-safe biasing resistors. Typical applications include industrial control networks, building automation, motor drive interfaces, and any RS-485 bus where the designer wants a through-hole package for prototyping or vibration-resistant socketing.
If your system uses 3.3 V logic, the receiver output is 5 V tolerant but the driver input thresholds are referenced to the 5 V supply; a level shifter or open-drain buffer is needed between a 3.3 V UART and the DI pin.
For dual-sourcing resilience, the base product number 65HVD485 covers several package and temperature variants; the 'EP' suffix denotes the extended temperature range in the PDIP package.
