General 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.

Key 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 CLK ↑ ↓ X Note: H: L: X: ↑: ↓: CLR L L H High level Low level Immaterial Low to high transition H.
