The 74HCT163D,652 is a counter/divider device that comes in the ubiquitous HCT logic family. It is a solid state logic gate that is designed to work under various conditions and provide reliable product performance. The device is a presettable synchronous up/down counter with a divide-by-2 and divide-by-8 section.

The device is ideal for applications requiring a count of up to 8-bits or a divide-by-N divider with as few as three logic stages. It is especially suited for applications where multiple, cascaded counters are required due to its synchronous operation and low power, integrated design. Furthermore, the device also offers a wide range of versatility when used in conjunction with other devices.

The 74HCT163D,652 is typically used in the fields of automotive, telecommunications, and industrial automation. Its versatile design makes it suitable for many applications, such as frequency division, rate generation, and pulse counting. The device can also be used as a divide-by-N divider in programmable logic controllers and for detecting alarms in power generation and transmission systems.

The device operates on a single +5V supply and has a 0-90 ns propagation delay time and a ± 5 ns output clock rise and falltime. The device also features a high-frequency operating range of 2.7 MHz maximum and is available in commercial, industrial, and automotive versions.

The 74HCT163D,652 is designed with three logic stages and two-input decoders and outputs eight bits (A-H) on a common bus. The device operates in either synchronous up or synchronous down mode as determined by the logic state of the terminal direction (DIR) input. The reset input (R) is used to preset the outputs to either low or high level. The device is available in 8-bit versions, 16-bit versions and higher if the cascading technique is employed, allowing for a wide range of versatility.

The device has a low power dissipation due to its TTL compatible output stage and can be powered by a single +5V supply voltage. The clocking of the device is obtained through the CLK input, which can be connected directly to an external clock source. The CLK and DIR inputs of the device must be connected together when cascading devices in order to maintain a coherent count sequence.

In summary, the 74HCT163D,652 is a versatile, synchronous up/down counter/divider with a divide-by-2 and divide-by-8 section. It has many application fields and is available in 8-bit versions, 16-bit versions and higher. The device is designed with a low power dissipation and offers a wide range of operation that is perfect for application requiring count of up to 8-bits or a N-divider.
