6.3 Feature Description

The TXH0137D-Q1 device is equipped with high drive open-drain outputs. These outputs are capable of sinking up to 100 mA each. In order to enable floating inputs, a 1-MΩ pull-down resistor exists on each channel. Also included at the input is a filtering circuit with a 50-kΩ series resistor to improve noise immunity and eliminate any erroneous switching.

Higher drive strength is achievable when multiple outputs are paralleled. Each output is equipped with over-voltage protection (OVP) diodes clamping to VCC. The diodes connected between the output and VCC pin is used to suppress any over-shoots caused by load reactance with the high current drive of this device.
