STMicroelectronics M74HC161TTR Integrated Circuit

The M74HC161TTR from STMicroelectronics is a high-speed CMOS 4-bit binary counter IC, belonging to the HC family, which offers a blend of high-speed operation with the low-power consumption characteristic of CMOS circuitry. This integrated circuit is designed to operate in a wide range of applications, from industrial to commercial, where reliable and efficient counting mechanisms are essential.

This binary counter features a synchronous reset function that enables the counter to be quickly and accurately reset to zero on the application of a high signal. Additionally, the device supports synchronous counting, which allows for precise count management and timing applications. The M74HC161TTR is capable of direct interfacing with the TTL (Transistor-Transistor Logic) family, thanks to its wide operating voltage range, which typically spans from 2V to 6V. This flexibility ensures that the counter can be integrated into a broad array of existing systems without compatibility issues.

Manufactured in a TSSOP16 package, the M74HC161TTR is designed for surface-mount technology, allowing for efficient PCB (Printed Circuit Board) space utilization. The compact form factor of the TSSOP (Thin Shrink Small Outline Package) enables designers to work with more complex circuit designs in smaller spaces, making it an excellent choice for space-constrained applications.

The counter comes with additional features such as a look-ahead carry output for high-speed counting cascades, two count enable inputs to allow for n-bit cascading, and a clock input which governs the timing of the counting operations. The robust design of the M74HC161TTR ensures that it can withstand the rigors of demanding environments while maintaining its performance integrity.

Overall, the M74HC161TTR from STMicroelectronics represents a reliable and versatile solution for designers who require a high-performance 4-bit binary counter. Its compatibility with various logic families, combined with its low power consumption and high-speed operation, makes it an essential component in digital systems where efficient counting is critical.
