HD74LV21A - Dual 4-input Positive AND Gates

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) Function Table Inputs A H L X X X B H X L X X C H X X L X D H X X X L Output Y H L L L L Note: H: High level L: Low le.
