1)Dear Sir, please answer. I'd like to use CD74HC165 register with 3.3V supply and I need to connect Q7 output of the CD74HC165 to the input of CD74AC14 (3.3V supply too). I will not have problems with this?
2) If I use 74AC series at 5V supply, then I can load output pin at 20 mA source current. If I use 74AC series at 3.3V supply, then can I load output pin at 20 mA source current (output pin in HIGH level and current flows from IC to GND via resistor) ?
TIA
Sincerely
Vladimir Naumenkov
