Notes:

Notes:

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at Vcc = 3.3V, 25

°C ambient.

3. This parameter is guaranteed but not tested.

4. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.

Notes:

1. See test circuits and waveforms.

See schematic example.

2. tpLH, tpHL, tsk(p), and tsk(o) are production tested. All other parameters guaranteed but not production tested.

3. Airflow of 1m/s is recommended for frequencies above 133MHz
