Part Number: SN74AXC4T774

Hi Team,

I have two questions about this device.

1. If I have a 10 kohm pullup resistor on any of the input pins, will this device work normally?

2. Is this device suitable for open-drain applications?

Thanks.

Roy

1. Yes, if the pull-up voltage reaches V_IH.

2. AXC inputs can be driven with open-drain signals (with pull-ups). AXC outputs are not open drain.
