Note that these inputs will default to an indeterminate T IN3, /IN3 state if left open. Unused differential input pairs can be terminated by connecting one input to V and the complementary input to GND through a 1k ? resistor. The V pin is to be CC T left open in this configuration. Please refer to the ?Input Interface Applications? section for more details. 3, 31, 26, 22 VT0, VT1, Input Termination Center-Tap: Each side of the differential input pair, terminates to a V T VT2, VT3 pin.

Inputs 30, 27, 25, 23, 21 IN1, /IN1, accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally IN2, /IN2, terminates to a V pin through 50?. Note that these inputs will default to an indeterminate T IN3, /IN3 state if left open. Unused differential input pairs can be terminated by connecting one input to V and the complementary input to GND through a 1k ? resistor. The V pin is to be CC T left open in this configuration. Please refer to the ?Input Interface Applications? section for more details. 3, 31, 26, 22 VT0, VT1, Input Termination Center-Tap: Each side of the differential input pair, terminates to a V T VT2, VT3 pin.
