HD74LV74AFP

The HD74LV74AFP has independent data, preset, clear, and clock inputs Q and Q outputs in a 14 pin package. The input data is transferred to the output at the rising edge of clock pulse CLK. 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.

The features of the HD74LV74AFP are: (1)VCC = 2.0 V to 5.5 V operation; (2)All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V); (3)All outputs VO (Max.) = 5.5 V (@VCC = 0 V); (4)Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C); (5)Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C); (6)Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V).

The absolute maximum ratings of the HD74LV74AFP are: (1)Supply voltage range: 0.5 to 7.0 V; (2)Input voltage range*1:  0.5 to 7.0 V; (3)Output voltage range*1, 2: 0.5 to VCC + 0.5  V; (4)Input clamp current: 20 mA; (5)Output clamp current: ±50 mA; (6)Continuous output current: ±25 mA; (7)Continuous current through: ±50 mA; (8)Maximum power dissipation at Ta = 25°C (in still air)*3: 785 mW; (9)Storage temperature: 65 to 150 °C
