Microcontroller part parameters

• (Hidden) supply voltage (VDD): 2 - 15V (Default = 5V)
• Output slope (Ohms): 25 ohms
• Output current (for 0.4 V drop on output (VDD = 5 V)): 16 mA
• Maximum voltage (for '0' input): 30% of VDD
• Minimum voltage (for '1' input): 70% of VDD
• Maximum output current: 50 mA
• Minimum input voltage: -1 V
• Maximum input voltage: VDD + 1 V

To ensure that an input voltage to a logic IC is recognised as a binary value, it must meet the specification Maximum voltage (for '0' input) or Minimum voltage (for '1' output), otherwise the input will have an undefined logic value.
