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.

Notes: The absolute maximum ratings are values, which must not individually be exceeded, and furthermore, no two of
which may be realized at the same time.
1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are
observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
