Description

1

OE or FS

Output Enable (OE) or Frequency Select (FS) pin.

The function of this pin is determined by the Ordering Information. When OE is selected, the

polarity of the OE is also selectable via ordering option. When FS is selected, the pin is a 3-

state (High, Mid (Float), Low) pin that selects on of the three factory-programmed

frequencies.

Note: The OE function stops the outputs in a differential state, it does not tri-state the outputs

or power down the internal circuitry.

2

FS or OE

Frequency Select (FS) or Output Enable (OE) pin.

The function of this pin is determined by the ordering options. When FS is ordered, the pin is

a 3-state (High, Mid (Float), Low) pin that selects on of the three factory-programmed

frequencies. When OE is selected, the polarity of the OE is also selectable via ordering

option. This pin is always the function not chosen for pin 1.

Note: The OE function stops the outputs in a differential state, it does not tri-state the outputs

or power down the internal circuitry.
