CD74HCT161M96 High-Speed CMOS Logic Presettable Counter by Texas Instruments

The CD74HCT161M96 is a high-speed CMOS Logic 4-bit binary counter crafted by the renowned semiconductor manufacturer Texas Instruments (TI). This integrated circuit (IC) belongs to the 74HCT family, which is known for its high-noise immunity and low power consumption, making it a staple in digital logic applications that require robust performance in a variety of conditions.

Designed for exceptional precision and reliability, the CD74HCT161M96 features synchronous counting and asynchronous presetting. The synchronous design ensures that the outputs change coincident with each other when so instructed by the count-enable inputs and the clock. The asynchronous preset feature allows the user to set the counter to a desired value instantaneously upon application of the preset-enable signal.

This IC is characterized for operation from -55°C to 125°C, providing a wide operating temperature range suitable for demanding environments. It is also compatible with TTL integrated circuits, allowing for easy integration into existing systems that utilize TTL logic.

The CD74HCT161M96 comes in a 16-pin SOIC package, providing a compact footprint that is ideal for space-constrained applications. The pin configuration includes the following: four data inputs (A, B, C, D), two count-enable inputs (P and T), a clock input (CP), a preset-enable input (PE), a ripple-carry output (RCO), and four parallel outputs (Q0 to Q3).

Key features of the CD74HCT161M96 include:

• 4-bit binary counter with synchronous count
• Asynchronous preset capability for quick initialization
• High noise immunity characteristic of CMOS devices
• Low power consumption
• Compatible with TTL outputs
• Wide operating temperature range: -55°C to 125°C
• 16-pin SOIC package for space-saving design

This product is ideal for use in a variety of applications, including industrial controls, automation systems, digital timers, frequency dividers, and any other system that requires reliable and precise counting functionality. With its robust design and compatibility with various logic families, the CD74HCT161M96 is a versatile choice for designers looking to incorporate a dependable counter into their electronic projects.
