Functional Description
• Quad 2-Input NAND Gate
General
The 74HC00D 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.
The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and
stable output.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
(1) High speed: tpd = 6 ns (typ.) at VCC = 5 V
(2) Low power dissipation: ICC = 1.0 μA (max) Ta = 25 
(3) Balanced propagation delays: tPLH ≈ tPHL
(4) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
