Functional Description
• Quad 2-Input NAND Gate (Open Drain)
General
The 74HC03D is a high speed CMOS 2-INPUT NAND GATE fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power
dissipation.
Pin configuration and function are the same as the 74HC00D. But the 74HC03D has, as its outputs, high
performance MOS N-channel transistors. (open-drain outputs) This device can, thefore, with a suitable pull-up
resistors, be used in wired-AND, LED driver and other application.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
(1) High speed: tpz = 5 ns (typ.) at VCC = 5 V
(2) Low power dissipation: ICC = 1.0 μA (max) at Ta = 25 
(3) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
(4) Open drain structure
