ON Semiconductor MC74HC161ADTG: 4-Bit Binary Counter

The MC74HC161ADTG is a high-performance, integrated circuit from ON Semiconductor, designed as a 4-bit binary counter. This device is a member of the high-speed CMOS family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits. This makes it an ideal choice for a wide range of counting applications in various electronic devices.

This binary counter features a fully synchronous state design, enabling it to perform all operations in synchrony with the positive edge of the clock signal. The MC74HC161ADTG is capable of direct clear, preset, count, and carry lookahead for cascading counters, which makes it highly versatile for complex counting solutions. Its synchronous reset function allows the counter to be reset to its initial state, ensuring precise control and timing of operations.

The device is equipped with four flip-flops and additional gating to provide a divide-by-two counter and a three-stage binary counter for which the count cycle length is divide-by-five. This allows for applications requiring non-standard count sequences, and it can be used in a variety of digital systems such as computers, robotics, and industrial controllers.

ON Semiconductor's MC74HC161ADTG comes in a 16-lead TSSOP package, making it compact and suitable for surface-mounted technology (SMT). It operates over a broad voltage range from 2V to 6V and offers a balanced propagation delay and transition times. This ensures reliable and fast performance across different voltage levels, which is critical for battery-operated and portable devices.

With its robust design and the ability to interface with other logic families, this binary counter is an excellent choice for designers looking for a reliable and efficient solution to complex timing and counting tasks in their digital applications. ON Semiconductor's commitment to quality ensures that the MC74HC161ADTG binary counter meets the stringent requirements of the modern electronics industry.
