1.2.4 OE Select

A 3x1 100-mil header provides access to the Output Enable (OE) pin on the device. The 100 mil jumper is available for selecting a known state for the OE pin if desired. The outer header pins access VCCA or GND through a 10 kΩ resistor. OE on TXS devices may be safely initialized to either VCCA or GND, although using a pull up resistor on OE during device power on may result in higher power consumption until VCCA is stable. Output enable pin is the input for the device and should never be left floating. The CMOS inputs must be held at a known state, either VCC or ground, to ensure proper device operation. Refer to Implications of Slow or Floating CMOS Inputs (SCBA004).
