The MC54HC4040J is a 12-stage binary ripple counter manufactured by Freescale Semiconductor - NXP. It features a clock input and a reset input, and provides 12 buffered outputs representing the binary count. The device is part of the HC (High-speed CMOS) family, offering a good balance of speed and power consumption.
Applications:
- Frequency division
- Timing circuits
- Address generation
- Control circuits
- Event counting
Features:
- High Speed: fMAX = 25 MHz (typ) at VCC = 5V
- Low Power Dissipation: ICC = 4 μA (max) at TA = 25°C
- High Noise Immunity: VNIH = VNIL = 28 % VCC
- Output Drive Capability: 10 LSTTL Loads
- Wide Operating Voltage Range: VCC = 2V to 6V
- 12 Buffered Outputs
- Asynchronous Reset
Benefits:
- Precise Frequency Division: Provides accurate division of input frequencies.
- Reduced Power Consumption: Low power operation is suitable for battery-powered or energy-sensitive applications.
- Robust Performance: High noise immunity minimizes the risk of false counting.
- Simple Reset Function: Asynchronous reset allows for easy initialization of the counter.
- Multiple Output Stages: 12 buffered outputs offer versatile counting and timing options.
Additional Details:
The MC54HC4040J operates over a wide temperature range, typically -55°C to +125°C, which suits it to demanding industrial and military applications. It is supplied in a ceramic Dual In-Line Package (DIP), providing good mechanical protection. The asynchronous reset allows the counter to be cleared regardless of the clock input. The 12 buffered outputs provide significant fan-out capability, allowing each output to drive multiple loads.
