CY74FCT245T: unused I/O pins

Kurumi Hasegawa

Part Number: CY74FCT245T

Hi team,

What should be done with unused I/O pins of CY74FCT245T?

I know there is a page discussing on this topic for other devices (here), but couldn’t find mentioning on this one.

Should I tie unused I/O pins to GND, without pulldown/pullup?

Best regards,

Kurumi

Unused inputs must have a valid logic level, either high or low. You can connect them directly to V_CC/GND or through a resistor.
