STMicroelectronics 74ACT163MTR Synchronous Presettable Binary Counter

The 74ACT163MTR from STMicroelectronics is a high-speed, synchronous, presettable binary counter that offers advanced performance in integrated circuit technology. Designed for use in counting applications, this device features a 4-bit binary counter with synchronous clear and preset capabilities. It is a part of the 74ACT series, which is known for its high-speed operation while maintaining the ability to interface with TTL-level logic devices.

This binary counter is capable of operating in two modes: count-up and clear. In count-up mode, the device counts up on each rising edge of the clock signal when the count enable inputs are in the active state. The clear function is synchronous, allowing the counter to be reset to zero on the clock pulse when the clear input is engaged. Additionally, the counter can be preset to any binary value across the four data input lines when the preset-enable input is activated.

Key features of the 74ACT163MTR include:

• High-speed operation: The device is capable of handling fast clock input frequencies, making it suitable for high-performance counting applications.
• Low power consumption: Despite its speed, the 74ACT163MTR maintains low power dissipation, which is ideal for energy-efficient designs.
• Wide operating voltage range: It operates over a broad voltage range, accommodating various system requirements.
• Output drive capability: The counter provides strong output drive capability, ensuring reliable operation even in heavy load conditions.
• Edge-triggered counting: The counter advances on the rising edge of the clock signal, providing precise control over the counting sequence.

The 74ACT163MTR is available in a surface-mount package, making it suitable for use in compact and high-density electronic assemblies. Its robust design and versatility make it an excellent choice for applications such as process control systems, digital timers, frequency dividers, and other digital logic systems where precise and reliable counting is required.

STMicroelectronics' commitment to quality ensures that the 74ACT163MTR meets the stringent requirements of modern electronic systems, providing designers with a reliable and efficient solution for their counting needs.
