SLLU379 March 2024 THVD4421
Refer to THVD4421 data sheet for most to up to date specification for device.
A selection of common usage ranges for devices considered in the construction of the board are shown below.
VCC input (at J6) is expected to be between 3V and 5.5V for compatible devices.
VIO input (at J7) is expected to be between 1.65V and 5.5V for compatible devices.
Signal inputs at J1-J4 are expected to be between 0V and VIO.
The device on-board does not generate voltages above VCC alone.
Each board is equipped with a 120 Ohm termination resistor Pad on each differential bus for RS-485 usage.
Voltage inputs for common mode signals R1-R4 must remain in the range -7V to 12V.
