Additional Details

The TC74HC393AF(EL) utilizes CMOS technology, providing a high level of noise immunity and low power consumption. Each counter stage has a toggle flip-flop configuration, dividing the input clock frequency by a factor of two. The reset input asynchronously clears all counter stages. The device is available in a small outline package (SOP), making it suitable for surface-mount assembly. The outputs are capable of driving CMOS, NMOS, and TTL logic levels.
