Description

The 74HC40103D is an 8-bit synchronous binary down counter from the 74HC series of high-speed CMOS logic ICs. It features a wide supply voltage range from 2V to 6V, making it suitable for various applications in digital electronics. The device can count down from a preset value and is often used in counting, timing, and frequency division applications.
Key features include:
- 8-bit Down Counter: Capable of counting from any preset value down to zero.
- Synchronous Operation: Ensures changes in the counter occur simultaneously with the clock signal, reducing the chance of errors.
- Preset Capability: The counter can be preloaded with a binary number, allowing it to start counting from any defined value.
- Carry Output: Generates a ripple carry output for cascading multiple counters.
- Control Inputs: Includes clock, enable, and up/down control inputs to manage and control the counting process effectively.
The 74HC40103D is ideal for use in digital systems requiring reliable and efficient counting mechanisms, offering a combination of simplicity and versatility.

Equivalent

The 74HC40103D is an 8-bit synchronous binary down counter.

Features

The 74HC40103D is an 8-bit synchronous binary down counter featuring several key attributes. It operates within a supply voltage range of 2V to 6V, making it compatible with a variety of systems. The counter can count down from any preset number, which is loaded via the parallel input, and it outputs a borrow flag when the count reaches zero. This device supports high-speed operation, with a typical propagation delay of around 20 ns at 5V. The 74HC40103D includes asynchronous master reset and clock enable inputs for flexible control and synchronization within digital circuits. Typical power consumption is low, making it suitable for battery-powered devices. The component is available in a variety of packages, including SO and TSSOP, which are suitable for surface mounting. Its Schmitt-trigger action inputs ensure better noise immunity, enhancing reliability in noisy environments. The 74HC40103D is widely used in applications requiring precise counting and timing, such as digital meters, frequency counters, and other sequential logic systems.

Pinout

The 74HC40103D is a 16-pin integrated circuit, functioning as an 8-bit synchronous binary down counter with a selectable reset. Here is the pin configuration:
1. Pin 1 (MR): Master Reset
2. Pin 2-9 (Q0-Q7): Parallel Output Pins (Q0-Q7)
3. Pin 10 (CEP): Count Enable Parallel
4. Pin 11 (CET): Count Enable Trickle
5. Pin 12 (PE): Parallel Enable
6. Pin 13 (CP): Clock Input
7. Pin 14 (TC): Terminal Count
8. Pin 15 (GND): Ground
9. Pin 16 (VCC): Positive Supply Voltage
The 74HC40103D is used for applications requiring digital counting processes, where it counts down from a preset value. The counter decrements synchronously with the clock signal. Upon reaching zero, the terminal count pin (TC) will indicate that the count cycle is complete. Master reset (MR) can asynchronously reset the counter to zero. This IC is useful in digital electronics for tasks like frequency division or event counting.
