Functional Description
• Hex Inverter (Open Drain)

General
The 74VHC05FT is an advanced high speed CMOS INVERTER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS
low power dissipation.
Pin configuration and function are the same as the 74VHC04FT, but the 74VHC05FT has high performance
MOS N-channel transistor. (OPEN-DRAIN outputs)
This device can, therefore, with a suitable pull-up resistors, be used in wired-AND, LED drive and other
applications.
An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage.
This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This
circuit prevents device destruction due to mismatched supply and input voltages.
