ControlNet™ TRANSCEIVER  
The third signal receiver function (SIG) provides a  
scaled analog output which is proportional to the  
differential voltage between XF1 and XF3. This  
output can be used for diagnostic purposes.  
FEATURES  
Compatible With the ControlNet Standard  
I/O Operates From 2.5-V to 5-V Supply  
Receiver thresholds within –120mV to 120mV  
Receiver hysteresis >50mV

These devices incorporate a differential receiver  
(RX) with the 120 mV sensitivity needed by  
ControlNet industrial applications.  
TXBAR  
A secondary receiver (CD) detects the presence of a  
valid positive differential signal.
