High-Speed Output Lines
The high-speed outputs can be used as either NPN (pull-down) or PNP (pull-up) 
lines. For NPN lines, the external load should be connected between the output 
and the positive supply voltage (<26.4V). The outputs pull down to less than 
3V when ON, which causes current to ow through the load. When the outputs 
are OFF, no current ows through the load.

Specification Description
Voltage 26.4V maximum through external load
Current 50mA maximum sink current
OFF state leakage current 100µA
External load resistance 240 Ohms to 10K Ohms
Each line rated at a maximum 50mA, protected against 
over-current, short circuits and transients from switching 
inductive loads. High current inductive loads require 
external protection diode. 
PTC 
Fuse
For PNP lines, the external load should be connected between the output 
and the negative supply voltage (0V). When connected to a 24VDC 
power supply, the outputs pull up greater than 21V when ON, and 
current ows through the load. When the outputs are OFF, no current 
ows through the load.
