ON Semiconductor MC74HC174A Hex D-Type Flip-Flop with Clear

The MC74HC174A is a high-speed, integrated circuit chip from ON Semiconductor, designed to provide efficient and reliable performance for a wide range of digital applications. This device is a member of the high-performance silicon-gate CMOS (Complementary Metal-Oxide-Semiconductor) family and features six D-type flip-flops with individual clear inputs.

Each flip-flop in the MC74HC174A has a separate direct clear (CD\) input and a D-type data input. The device operates on the edge-triggered mechanism, capturing data on the rising edge of the clock signal. Once the clock input (CP) goes from low to high, the data present at the D inputs is transferred to the Q outputs. The clear function is asynchronous, meaning it is independent of the clock input and, when activated, will set the Q outputs to a low state regardless of any other input condition.

This versatile IC is designed to interface with standard logic families and is suitable for a variety of uses, including control registers, shift registers, and flip-flop-based functions. The MC74HC174A's CMOS technology offers significant power savings over its TTL (Transistor-Transistor Logic) counterparts, making it a preferred choice for battery-operated devices, portable equipment, and other power-sensitive applications.

The MC74HC174A operates over a broad voltage range from 2V to 6V and features a standardized symmetrical output drive, which provides both high sink and source capability. This ensures compatibility with a wide array of interfacing products and helps to simplify system design. Furthermore, the chip boasts low power consumption and balanced propagation delays, contributing to its overall efficiency.

With its robust latch-up performance, the MC74HC174A exceeds 100mA per JESD 78 Class II standards, ensuring reliability even under stress conditions. Packaged in a variety of options, including SOIC, TSSOP, and PDIP, the MC74HC174A provides flexibility in hardware design and is suitable for automated assembly processes.

For engineers and designers looking for a reliable flip-flop solution, the ON Semiconductor MC74HC174A offers a blend of performance, power efficiency, and design flexibility, making it an excellent choice for advanced digital systems.
