THVD1420DR

The THVD1420DR is a half-duplex RS-485/RS-422 transceiver from Texas Instruments, designed for robust industrial communication. It features ±18V bus fault protection, ESD protection (±16kV HBM), and supports data rates up to 20Mbps.
Key highlights:
- 3.3V or 5V supply operation.
- Low-power shutdown mode (1µA typical).
- High noise immunity with failsafe receiver inputs.
- Industrial temp range (–40°C to +125°C).
Ideal for factory automation, motor control, and harsh environments, the THVD1420DR ensures reliable data transmission over long distances. Its small SOIC-8 package makes it suitable for space-constrained designs.
