Digital Outputs 4.10.
Output type: Open drain, not isolated, internal 1.2 kOhm pull-up and diode to 5 V
Note: Pull-ups design with diode enables direct driving TTL inputs, but it's not intrusive when
driving high voltage loads

Switched voltage max: 40 V
Maximal switching frequency: 100 kHz
Rise time to 5/24 V, 1 kOhm load: to be specified
Fall time to 5/24 V, 1 kOhm load: to be specified
Driver fault tolerance: current limit 1.7 A, thermal shutdown, short circuit protection, peak
overvoltage protection
Driver type: VNS1NV04DP-E
