HD74LV20A
Dual 4-input Positive NAND Gates
ADE-205-254 (Z)
1st Edition
March 1999
Description
The HD74LV20A performs the Boolean functions Y = ABCD or Y = A+B+C+D in positive logic.
Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook
computers), and the low-power consumption extends the battery life.
Features
VCC = 2.0 V to 5.5 V operation
All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
All outputs VO (Max.) = 5.5 V (@VCC = 0 V)
Typial VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
Typial VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C)
Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V)

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore,
no two of which may be realized at the same time.
1. The input and output voltage ratings may be exceeded even if the input and output clamp-current
ratings are observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
