Description

The CD4040BE is a binary ripple counter and a 12-stage binary counter integrated circuit (IC) designed for counting applications. It belongs to the CD4000 series of CMOS (Complementary Metal-Oxide-Semiconductor) logic devices, known for low power consumption and high noise immunity. The CD4040BE can count in binary from 0 to 4095 (2^12 - 1) and features a number of outputs (Q0 to Q11) representing the count value.
Key features include:
- Wide supply voltage range (3V to 15V).
- Low power dissipation.
- Asynchronous reset pin for setting the counter back to zero.
- Cascadable architecture allowing multiple devices to be connected for higher counting capabilities.
The CD4040BE is commonly used in timing applications, frequency dividers, and digital clocks, making it a versatile component in electronic design. It is typically available in a 14-pin dual in-line package (DIP) or surface-mount configurations.

Features

The CD4040BE is a binary ripple counter IC that features a 12-stage binary counter, capable of counting from 0 to 4095. It operates with a wide supply voltage range of 3V to 15V, making it suitable for various applications. Key features include:
1. Count Mode: It can count in a binary format and can be reset asynchronously.
2. Output: The IC offers multiple output bits (Q1 to Q12) for counting, with each output representing a binary stage.
3. Clock Input: It has a single clock input for counting pulses.
4. Low Power Consumption: Designed for efficient operation, it consumes low power during counts.
5. TTL Compatible: The outputs are compatible with TTL logic levels.
6. Integrated Logic: Contains internal flip-flops and counters, simplifying design.
This makes the CD4040BE suitable for applications in digital clocks, frequency dividers, and event counters.

Package

The CD4040BE is typically packaged in a 14-pin dual in-line package (DIP) format. It may also be available in surface mount packages like SOIC or TSSOP, depending on the manufacturer. The DIP package allows for easy insertion into breadboards and sockets.

Pinout

The CD4040BE is a 12-stage binary ripple counter with a total of 13 pins. Here are the key pin functions:
1. VDD (Pin 1): Positive power supply (typically +3V to +15V).
2. GND (Pin 2): Ground reference.
3. Q1 to Q12 (Pins 3-14): Output pins representing binary count states from 1 to 12.
4. Reset (Pin 15): Active-high reset to clear the counter.
5. Clock (Pin 10): Input for the clock signal; the counter increments on the rising edge.
6. Carry Out (Pin 11): Output that indicates when the counter has reached its maximum count (typically when it rolls over from 15 to 0).
This IC can be used in various applications, including frequency division and digital counting.
