SN74LXC1T14: Some question about datasheet data...

Peter Tseng
Genius 5555 points
Part Number: SN74LXC1T14

Dear Sirs,

Please help with the questions below.

Thanks.

1. May I know what the value it is?

2. If Vcc is 3.3V, and Vi is less than 2.7V(3.3V-0.6V), the current will be 50~75uA, and if Vi is more than 2.7V, the current will be 3~6uA, right?

    1. The typical value is near zero.

    2. These values are valid only for the specified test conditions, i.e., if the input voltage is exactly at 3.3 V or at 2.7 V.

    The additional input supply current has a curve similar to that in your earlier question. Voltages near VCCI are no problem, and logic signal usually are near VCC.
