The MC14040BCL is a 12-Stage Binary Counter manufactured by Freescale Semiconductor (now NXP). This CMOS integrated circuit is a fully static counter meaning the clock can be stopped. This device is frequently used as a frequency divider or for time-delay generation. It utilizes master-slave flip-flops to implement the counting function. All outputs are buffered.

Applications:

• Frequency dividers
• Time delay generation
• Sequencers
• Digital timers
• Control systems

Features:

• 12-Stage Binary Counter
• Fully Static Operation
• Buffered Outputs
• Wide Operating Voltage Range: 3.0V to 18V
• Low Power Consumption
• High Noise Immunity

Benefits:

• Provides a range of division ratios from 2 to 4096
• Simple to implement frequency division or time delays.
• Low power consumption extends battery life
• High noise immunity allows usage in noisy environments

Additional Details:

The MC14040BCL is available in a 16-pin DIP package. All stages are accessible which is helpful for complex division schemes. The counter advances on the negative transition of the clock input. A master reset input clears all counters. Datasheets and application notes including suggested components and example circuits are widely available.
