† All typical values are at VCC = 3.3 V, TA = 25°C.

‡ For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.

§ Unused pins at VCC or GND

¶ This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.
