Overview
Description
The THVD1452DGSR is a 3.3V/5V half-duplex RS-485/RS-422 transceiver from Texas Instruments. It supports data rates up to 20 Mbps and features ±16kV ESD protection (HBM), making it robust for industrial applications.
Key features:
- Wide supply range: 3V to 5.5V
- Low power: 1.5mA (active), 1µA (shutdown)
- Failsafe receiver (ensures logic-high output on open/bus idle)
- 50Ω driver output impedance for reduced reflections
Ideal for industrial automation, motor control, and long-distance communication, it comes in a 10-pin VSSOP (DGS) package.
For more details, refer to the datasheet on TI’s website.
