Quad 2-Input NAND Gate (open drain)

   The TC74VHC03 is an advanced high speed CMOS 2-INPUT NAND GATE 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 TC74VHC00. But the TC74VHC03 has, as its outputs, high performance MOS N-channel transistors. (OPEN-DRAIN outputs) This device can, therefore, with a suitable pull-up resistors, be used in wired-AND, LED driver and other application.

   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.
