ON Semiconductor MC74HC393ADR2G Dual Binary Counter

The MC74HC393ADR2G is a high-performance integrated circuit designed and manufactured by ON Semiconductor, a leader in energy-efficient innovations. This device is part of the 74HC series and is a dual 4-stage binary ripple counter with a wide operating voltage range and high noise immunity characteristic of the HC family. It is a versatile component used in a variety of electronic applications, including timing circuits, counters, and frequency dividers.

The MC74HC393ADR2G is constructed with silicon gate CMOS technology which ensures low power consumption and a reliable performance. The counter advances on the negative-going edge of the clock signal, which is a common feature in digital electronics, providing precision and stability in timing-related tasks. Additionally, the reset inputs are asynchronous, allowing the counters to be reset independently and quickly regardless of the clock state.

Each counter contains a four-stage ripple-carry binary counter and features a two-input NAND gate which allows the counters to be cascaded. This cascading capability makes it possible to create longer count sequences or more complex counting arrangements as needed for specific applications.
