If left floating, pin defaults to V
open. See “Input Interface Applications” section for single-ended inputs.
Bias Reference Voltage: V
ended inputs or AC-coupling to the IN, /IN inputs. Limit sink / source
GND and Exposed pad must be tied to ground plane.
Single-ended LVTTL Output: Defaults to LOW if IN inputs left open.
Positive Power Supply: Bypass with 0.1 F//0.01 F low ESR capacitors.
