The TC74HC393AP is a high-speed CMOS dual 4-stage binary counter manufactured by Toshiba Semiconductor and Storage. It features two independent 4-stage binary counters, each capable of dividing the input frequency by 2, 4, 8, and 16. These counters are cascadable, enabling the creation of larger division ratios. The device is designed for timing, frequency division, and control applications requiring binary counting.

Additional Details

The TC74HC393AP comprises two independent 4-stage binary counters. Each counter has a clock input (1CK and 2CK) and a master reset input (1MR and 2MR). The counter advances on the negative-going transition of the clock input. A high level on the master reset input clears all outputs to a low state. The device is packaged in a DIP14 package.
