ON Semiconductor MC74HC4040N 12-Stage Binary Ripple Counter

The ON Semiconductor MC74HC4040N is a high-performance, integrated circuit designed to function as a 12-stage binary ripple counter. This device is a part of the high-speed CMOS logic family and is known for its robustness and versatility in a wide range of counting applications. With the ability to operate from a wide voltage range, the MC74HC4040N is suitable for use in systems that require low power consumption and high noise immunity.

Constructed with silicon gate CMOS technology, the MC74HC4040N offers significant improvements over standard logic types while maintaining the ability to interface with standard TTL logic. The counter advances on the negative-going edge of the clock signal, which is supplied to the CP (Clock Pulse) input. A built-in oscillator buffer is provided to facilitate external clock generation.

The device features 12 flip-flops with intermediate taps at stages 6, 7, 8, and 12. These taps provide additional outputs which can be used for timing signals or to trigger external circuits at different stages of the count. The counter can be reset to its zero state by applying a high voltage to the RESET input, which immediately terminates the counting and sets all outputs low.

Key specifications of the MC74HC4040N include:

• Supply Voltage Range: 2V to 6V
• High Noise Immunity Characteristic of CMOS Devices
• Low Power TTL Compatibility: Fan Out of 2 Driving 74L or 1 Driving 74LS
• Maximum Clock Frequency: 24MHz at 6V
• Low Power Consumption: 20 µA Maximum Icc at 25°C
• Standardized, Symmetrical Output Characteristics
• 12 Stages of Ripple-Carry Binary Counting
• Additional Buffered Outputs from Stages 6, 7, 8, and 12

Available in a 16-pin DIP (Dual In-line Package), the MC74HC4040N is easy to integrate into both prototyping and production circuits. Its robust design ensures reliable operation in a variety of environmental conditions, making it an excellent choice for designers looking for a dependable counter solution. Whether used in digital clocks, frequency dividers, counters, or as a component in more complex digital systems, the ON Semiconductor MC74HC4040N delivers performance that engineers can trust.
