RFW-D100
Vishay RFWaves
Note 1: All input pins are Schmitt-trigger inputs.
Note 2: All output pins that are marked with ‘*’ (DATA_IO, RF_ACTIVE, TX_RX) have a 2 mA output buffer. The rest
of the output pins have an 8 mA output buffer.
Note 3: For each input pin or bi-directional pin in input mode, in the Type column: (D) specifies a pull-down, (U) spec-
ifies a pull-up, and (X) specifies no internal pull-up or pull-down.
