STMicroelectronics HCF4017BEY Decade Counter/Divider

The HCF4017BEY is a high-quality integrated circuit from STMicroelectronics, designed to function as a decade counter/divider with 10 decoded outputs. This versatile component is a monolithic, complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement mode transistors. It is widely used in a variety of applications ranging from counting operations to sequential logic control, making it an essential component in the field of digital electronics.

At the heart of the HCF4017BEY lies its ability to count pulses. It features a 5-stage Johnson decade counter with ten spike-free decoded outputs as well as an output from the most significant flip-flop. Each decoded output remains high for one full cycle of the clock and is sequenced by a low-to-high transition of the clock input. Additionally, the HCF4017BEY includes a reset function that overrides all other inputs, initializing the decade counter to the zero state.

The HCF4017BEY operates over a wide voltage range from 3V to 18V and offers maximum flexibility in power supply specifications. This broad voltage range ensures compatibility with a variety of digital systems and allows for use in applications that require different voltage levels. The low power consumption characteristic of CMOS circuitry, along with its static operation, makes this counter/divider an energy-efficient solution for modern electronic designs.

Constructed in a 16-pin dual-in-line package, the HCF4017BEY is easy to integrate into printed circuit boards. The compact form factor contributes to a reduction in overall board space without compromising functionality. Its robust design ensures a high degree of durability and reliability, which is crucial for applications that demand consistent performance over time.

Whether used for creating timing circuits, LED sequencers, or implementing simple state machines, the HCF4017BEY from STMicroelectronics stands out as a high-performance, versatile component suitable for a wide array of digital applications.
