Termination Impedance Select
Hardware Mode Only
The TERSEL pin is used to select the transmitter and receiver impedance. By
default, the impedance is set to 75.
"Low" = 75
"High" = 120
N
Factory Test Mode
For normal operation, the TEST pin should be tied to ground.
N
In Circuit Testing
When this pin is tied "Low", all output pins are forced to "High" impedance for in cir-
cuit testing.
