TTL Digital Output
A digital input/output (DI/O) channel can be configured by software to perform digital
input measurement, which is the power-on default configuration, or digital output
generation. When performing digital output generation, a voltage logic level is gener

nal. This is shown in Figure 2.8.
Figure 2.8 Digital output signal connection.
Each digital output channel can source or sink only finite amount of current. If this
limit is exceeded, the output voltage will not stay in the specified voltage logic level.
Refer to the device specifications for the maximum source and skin current values.
