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 50ï to VT = VCC - 2V, the QB load is terminated 50ï 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.
