The CD74HC4017M96 is a synchronous 5-bit counter, divide-by-10 counter, with one synchronous reset input, and a single strobe input. This device has a synchronous master reset which overrides all other inputs, independently of the logic levels of the clocks and other inputs. The CD74HC4017M96 is a high speed, low power CMOS logic integrated circuit which is fabricated with sub-micron silicon gate and double-level metal wiring C2MOS technology.

Application Field

The CD74HC4017M96 synchronous 5-bit counter is ideal for applications like frequency divider, decade counters, digital counters, data acquisition, and control applications. It can be used to count from 0 to 9 and is capable of counting up to 999 in a cascaded system. This device can also be used in applications such as pulse-width modulation and serial data communication.

The CD74HC4017M96 is a versatile logic device that is capable of performing multiple tasks in a single circuit. Its ability to count up to 999 in either direction and to operate at high frequencies make it an excellent choice for designers looking for a low-power logic solution. Additionally, its synchronous master reset capability allows it to maintain system integrity even when exposed to unexpected levels of input voltages.

The CD74HC4017M96 is also used in various consumer electronic applications, from industrial to home structures. Examples include speech recognition, digital alarm clock systems, audio mixing devices, video game consoles, car audio systems, and digital signage systems.

Working Principle

The CD74HC4017M96 is a synchronous 5-bit counter that can be used to count up to 9. It has a master reset input (MR) which overrides all other inputs, independently of the logic levels of the clock and other inputs. When the master reset is activated, the counter is reset back to its initial state. The reset input also allows for the resetting of the counts when the count reaches 9.

The CD74HC4017M96 consists of five flip-flops connected in series, that are triggered with each clock cycle. The flip-flops output each bit of the count sequence with each clock cycle. The number of full cycles it takes for the count to reset to zero is referred to as the ‘Modulus Count’. The modulus count can be set from 2 (for a 4-bit count) up to 10 (for a 5-bit count) by employing appropriate combination of inputs. The most commonly used modulus count is 10 (5-bit).

The CD74HC4017M96 can also be used as an up/down counter. The up/down input control line sets the counter to count up (with rising clock edges) or count down (with falling clock edges). The direction of the count (up/down) is determined by the logic level of the control line.

The CD74HC4017M96 is capable of counting up to 999 with a single clock. To achieve this, it can be cascaded with other counters, allowing for the construction of arbitrarily large counting systems. This device can be used with other compatible logic devices to form a variety of complex ripple, presettable, or synchronous counting sequences.
