NOTE 1. Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the
device is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications
after thermal equilibrium has been reached under these conditions.
NOTE 2. QA is terminated 50 to VT = VCC - 2V, the QB load is terminated 50 to VCC/2.
NOTE 3. For single-ended LVCMOS input applications, refer to the Applications section Wiring the Differential Input Levels to Accept Sin-
gle-ended Levels.
NOTE 4. VIL should not be less than -0.3V. VIH should not be higher than VCC.
