HD74LV21A
Dual 4-input Positive AND Gates
REJ03D0237–0300Z
(Previous ADE-205-255A (Z))
Rev.3.00
Jun. 01, 2004
Description
The HD74LV21A performs the Boolean functions Y = A•B•C•D 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)
• 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)
