- ±16-V bus fault protection (absolute max voltage on bus pins)
- Extended industrial temperature range: -40°C to 125°C
- Low power consumption
- Shutdown supply current < 5 µA
- Quiescent current during operation < 3 mA
- Glitch-free power-up/power-down for hot plug-in capability
- Open, short, and idle bus failsafe
- 1/8 Unit load (Up to 256 bus nodes)
- Small, space-saving thermally efficient 10-pin VSON package (3 mm x 3 mm)
The bus pins are immune to high levels of IEC Contact Discharge ESD events, eliminating the need for additional system level protection components. The device operates from a single 3-V to 5.5-V supply. The wide common-mode voltage range and low input leakage on bus pins makes the device suitable for multi-point applications over long cable runs.
THVD1454 is available in space-saving thermally efficient 10-VSON package (3 mm x 3 mm). The device is characterized for ambient temperature from –40°C to 125°C.
