CD74HC192EG4

The CD74HC192EG4 is a high-speed CMOS binary counter integrated circuit produced by Texas Instruments. It is part of the 74HC family, which is known for its high-speed performance and low power consumption. Here’s a detailed description of its features and specifications:

General Features:

• Type: 4-bit binary counter
• Technology: High-speed CMOS
• Functionality: The CD74HC192 can count in binary from 0 to 15 (0000 to 1111 in binary) and can be configured for up/down counting.
• Count Control: It includes control inputs for enabling counting, resetting, and setting the count direction (up or down).
• Synchronous Operation: The counter operates synchronously, meaning all changes in the output occur simultaneously with the clock signal.

Pin Configuration:

• The IC typically comes in a 16-pin dual in-line package (DIP) or surface mount package, with each pin serving a specific function:
  • Clock Input (CLK): The clock signal that triggers counting.
  • Up/Down Control (U/D): Determines the counting direction.
  • Reset (MR): Asynchronous reset input to set the counter to zero.
  • Load (LD): Allows loading a preset value into the counter.
  • Data Inputs (D0-D3): Used for loading a preset value when the Load input is active.
  • Count Outputs (Q0-Q3): The binary output representing the current count value.
  • Carry Out (CO): Indicates when the counter has overflowed (counted past 15).

Electrical Characteristics:

• Supply Voltage (Vcc): Typically operates at 2V to 6V, making it compatible with a wide range of digital systems.
• Input Voltage Levels: Compatible with standard TTL logic levels, ensuring easy integration with other digital components.
• Propagation Delay: Fast switching times, typically in the range of nanoseconds, allowing for high-speed applications.

Applications:

• The CD74HC192 is widely used in digital applications such as:
  • Frequency counters
  • Digital clocks
  • Event counters
  • Timer circuits
  • Any application requiring binary counting or frequency division.

Advantages:

• Low Power Consumption: The CMOS technology allows for low static power consumption, making it suitable for battery-operated devices.
• High Noise Immunity: The design provides good noise margins, ensuring reliable operation in various environments.
• Versatile Functionality: The ability to count up or down and load preset values makes it adaptable for different counting applications.

Package Information:

• The CD74HC192EG4 is often available in a RoHS-compliant package, ensuring it meets environmental standards for lead-free electronics.

In summary, the CD74HC192EG4 from Texas Instruments is a versatile and efficient 4-bit binary counter that is ideal for a variety of digital counting applications, offering high-speed performance and low power consumption in a compact package.
