Product Summary

The HD74LV21A is a Dual 4-input Positive AND Gate. The HD74LV21A performs the Boolean functions Y = A•B•C 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.

Parametrics

HD74LV21A absolute maximum ratings: (1)Supply voltage range VCC: –0.5 to 7.0 V; (2)Input voltage range VI: –0.5 to 7.0 V; (3)Output voltage range, VO: –0.5 to VCC + 0.5V; (4)Input clamp current IIK: –20mA; (5)Output clamp current IOK: ±50mA; (6)Continuous output current IO: ±25mA; (7)Continuous current through VCC or GND ICC or IGND: ±50mA; (8)Maximum power dissipation at Ta = 25℃ (in still air) PT: 785mW; (9)Storage temperature Tstg: –65℃ to 150℃.

Features

HD74LV21A features: (1) VCC = 2.0V to 5.5V operation; (2) All inputs VIH (Max.) = 5.5V (@VCC = 0V to 5.5V); (3) All outputs VO (Max.) = 5.5V (@VCC = 0V); (4)Typical VOL ground bounce<0.8V (@VCC = 3.3V, Ta = 25℃); (5)Typical VOH undershoot>2.3V (@VCC = 3.3V, Ta = 25℃); (6)Output current ±6mA (@VCC = 3.0V to 3.6V), ±12mA (@VCC = 4.5 V to 5.5V).
