DM74LS163AN - Synchronous 4-Bit Binary Counter

The DM74LS163AN is a high-speed synchronous, presettable 4-bit binary counter designed and manufactured by ON Semiconductor. This integrated circuit (IC) provides a reliable and efficient solution for digital counting applications. It is widely used in various electronic systems for counting purposes, including computers, robotics, industrial machines, and more.

This counter features a fully synchronous internal architecture, which means that the output changes occur on a predictable clock edge. This makes the DM74LS163AN ideal for applications requiring precise timing and control. The synchronous design also allows for higher counting speeds without the risk of ripple delays that can occur with asynchronous counters.

The device includes a clear function, which resets the counter to zero when applied, and preset inputs that allow the counter to be set to any desired value. It operates with a typical clock frequency of up to 80MHz, ensuring that it can handle high-speed counting tasks with ease. The DM74LS163AN also has a carry output, which can be used to cascade multiple counters for extended count ranges.

Constructed with low-power Schottky technology, the DM74LS163AN offers a balance of speed and power efficiency. It is provided in a 16-pin dual-in-line package (DIP), making it suitable for through-hole mounting on printed circuit boards (PCBs). The device operates over a wide voltage range and is compatible with standard TTL (Transistor-Transistor Logic) signal levels, ensuring easy integration into existing digital systems.

Key features of the DM74LS163AN include:

• Fully synchronous operation for greater reliability
• Internal carry lookahead for cascading
• Synchronous reset and preset capability for greater control
• Low power consumption with Schottky technology
• High-speed performance with a maximum count frequency of 80MHz
• Standard TTL compatibility

With its robust design and versatile features, the DM74LS163AN from ON Semiconductor is an excellent choice for designers looking to implement a reliable and high-speed counting solution in their digital systems.
