PIN DESCRIPTIONS

DISCNCT: Taking this pin low causes the 18 channels to

become high impedance and the chip to go into

low-power mode; a high or open state allows the

channels to provide normal termination.

GND: Ground reference for the IC.

LINE1–LINE18: 110

termination channels.

REG: Output of the internal 2.8V regulator.

TRMPWR: Power for the IC.
