7.2.2.2 High-Impedance Input Drivers

The TXH0137D-Q1 features a 1-MΩ input pull-down resistor. The presence of this resistor allows the input drivers to be tri-stated. When a high-impedance driver is connected to a channel input, the TXH0137D-Q1 detects the channel input as a low-level input and remains OFF. The input noise rejection circuit helps improve noise tolerance levels if necessary, when input drivers are in the high-impedance state.
