SN74LVC16T245: Output capacitance.

Kengo.Y

Part Number: SN74LVC16T245

Hi team.

My customer wants to put in capacitance at the output for noise.
How much capacity can I insert?

The datasheet says it is 10pF(MAX). Is my understanding correct?

If it is correct, how about capacity when other VCC.

Sincerely.
Kengo.

Section 4.6.30 of Understanding and Interpreting Standard-Logic Data Sheets says that C_io is

the capacitance of an input/output (I/O) terminal of the device with the input conditions applied that, according to the product specification, establishes the high-impedance state at the output.

When an output is active, its capacitance cannot be measured.

Anyway, the maximum capacitance that can be connected directly is 70 pF; larger capacitors are allowed if your circuit limits the output current so that it stays below the absolute maximum ratings. See [FAQ] What is the maximum capacitive load that a logic device can drive?
