HD74LV27A
Triple 3-input Positive NOR Gates
ADE-205-256 (Z)
1st Edition
March 1999
Description
The HD74LV27A performs the Boolean functions Y = Aâ¢Bâ¢C or Y = A+B+C 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)
⢠Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
⢠Typical 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)
