HD74LV4040A
12-stage Binary Counter
ADE-205-282 (Z)
1st Edition
April 1999
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.
