Dual 4-bit Binary Counters

Description
The HD74LV393A contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-
256 counter.
The HD74LV393A is incremented on the high to low transition (negative edge) of the clock input, and each has an
independent clear input. When clear is set high all four bits of each counter is set to a low level. This enables count
truncation and allows the implementation of divide-by-N counter configurations.
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.
