NOTES:

3. Unused inputs should be tied to VCC through a pullup resistor of approximately 5 kW or greater to prevent them from floating. Refer

to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.

4. All VCC and GND pins must be connected to the proper-voltage power supply.

† Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms.

‡ This is the increase in supply current for each input that is at one of the specified TTL-voltage levels rather than 0 V to VCC.
