Frequently Asked Questions
What type of counter is the CD74HC40103EE4?
The CD74HC40103EE4 is an 8-bit synchronous binary down counter, meaning it decrements its count value on each clock edge from a preset value down to zero, at which point the Terminal Count Output (TCO) is asserted.
What is the Terminal Count Output (TCO) feature?
The Terminal Count Output (TCO) is a signal that activates when the counter reaches its terminal count (zero in down-counting mode), enabling easy cascading of multiple CD74HC40103EE4 devices to form wider counters or generate synchronization pulses in timing circuits.
Can the CD74HC40103EE4 be preset to any starting count value?
Yes, the CD74HC40103EE4 includes a load/preset input that allows the counter to be loaded with any 8-bit binary value (0 to 255), enabling programmable count sequences and flexible time-delay generation tailored to specific application requirements.
What package does the CD74HC40103EE4 come in?
The CD74HC40103EE4 is available in a 16-pin PDIP (Plastic Dual In-line Package) through-hole format, making it suitable for breadboard prototyping, educational lab work, and through-hole PCB designs in timing and counting applications.
What are typical applications for the CD74HC40103EE4?
Typical applications include programmable time-delay circuits, frequency prescalers, event counters, industrial sequencing controllers, and cascaded multi-stage counter chains in digital electronics where 8-bit synchronous down counting with preset capability is required.
