ON Semiconductor 74ACT161MTCX: Synchronous Presettable Binary Counter
The 74ACT161MTCX from ON Semiconductor is a high-performance, CMOS synchronous presettable binary counter designed for use in a wide range of electronic applications requiring precise counting capabilities. This integrated circuit (IC) is part of the 74ACT series, which is renowned for its high-speed operation and compatibility with TTL (Transistor-Transistor Logic) levels.
Featuring a 4-bit binary counter, the 74ACT161MTCX provides users with the ability to implement synchronous counting operations. The counter advances on the rising edge of the clock signal when the count enable input is in the active state. Additionally, the device includes a synchronous reset function that allows the counter to be quickly set to zero when required, which is essential for applications that demand rapid initialization or resetting of the count value.
The 74ACT161MTCX is equipped with a preset feature that enables the counter to be loaded with a preset value in parallel, providing flexibility for various counting sequences. This functionality is particularly useful in applications where specific count values are required to trigger events or actions within a system.
With its wide operating voltage range of 4.5V to 5.5V, the 74ACT161MTCX is suitable for interfacing with both 5V logic families, ensuring seamless integration into mixed-voltage systems. The device also boasts low power consumption, which makes it an ideal choice for power-sensitive applications.
Packaged in a compact TSSOP-16 (Thin Shrink Small Outline Package), the 74ACT161MTCX offers a space-saving solution for modern electronic designs where board real estate is at a premium. The small footprint of the package does not compromise the performance or functionality of the IC, making it a preferred choice for designers looking to optimize their circuit layouts.
In summary, the ON Semiconductor 74ACT161MTCX is a versatile and reliable binary counter that provides high-speed operation, synchronous counting, easy presetting, and reset capabilities, all within a small form factor package. Its compatibility with TTL logic levels and low power requirements make it an excellent choice for a broad range of counting applications in industrial, commercial, and consumer electronics.
