Description
The HD74LV4040A is a 12 stage counter. This device is incremented on the falling edge (negative transition) of the
input clock, and all its output is reset to a low level by applying a logical high on its reset input. 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)
