Dual 4-Input NAND Gate
The TC74AC20 is an advanced high speed CMOS 4-INPUT
NAND GATE fabricated with silicon gate and double-layer metal
wiring C²MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL 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
• High speed: t_pd = 4.1 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Symmetrical output impedance: |I_OH| = I_OL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• ^{Balanced propagation delays: t}pLH ^{∼− t}pHL
• Wide operating voltage range: V_CC (opr) = 2~5.5 V
• Pin and function compatible with 74F20
