9.2.1.3 Output Considerations

The positive supply voltage is used to produce the output HIGH voltage. Drawing current from the output will decrease the output voltage as specified by the VOH specification in the GUID-603877D3-0201-4D44-B7EA-5BAC6394C625.html#GUID-603877D3-0201-4D44-B7EA-5BAC6394C625. Similarly, the ground voltage is used to produce the output LOW voltage. Sinking current into the output will increase the output voltage as specified by the VOL specification in the GUID-603877D3-0201-4D44-B7EA-5BAC6394C625.html#GUID-603877D3-0201-4D44-B7EA-5BAC6394C625.

Unused outputs can be left floating. Do not connect outputs directly to VCC or ground.

Refer to GUID-209ED634-1803-435E-8571-7F1FCFD3BBC1.html#GUID-209ED634-1803-435E-8571-7F1FCFD3BBC1 for additional information regarding the outputs for this device.
