Additional Details

The 74V393MTC is typically available in a SOIC (Small Outline Integrated Circuit) package. Each counter has a clock input and a reset input. The outputs are the four bits of the binary count. The asynchronous reset allows immediate clearing of the counter, independent of the clock signal. The 74V series typically operates at higher speeds and lower power compared to older TTL families.
