Hi,

what is the max data rate our SH74AHC125 could support?

Any application or situation limiting?

Good morning Shuang,

The maximum operating frequency can be estimated by finding the rise time using f = 1/2Π*2.2RC. With a load capacitance of 15pF and a load resistance of 100kOhm the max data rate would be approximately 48 MHz.

Best regards,

Sebastian
