Additional Details

The PI74FC374ATSX is an octal D-type flip-flop featuring three-state outputs, designed for high-performance applications requiring fast data storage and retrieval. The device integrates eight individual D-type flip-flops, each capable of storing one bit of data. Data is entered into the flip-flops on the positive-going edge of the clock (CLK) input. The three-state outputs allow the device to be easily connected to a bus without loading the bus when not actively driving it. This is controlled by the output enable (OE) input; when OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state.

The PI74FC374ATSX operates from a 5V supply and is TTL compatible, making it easy to integrate into existing systems that use TTL logic. The device provides a cost-effective solution for applications requiring fast data storage, such as memory systems, address latching, and buffer registers. The positive-edge triggered clock ensures reliable data capture. The SOIC package facilitates surface-mount assembly, allowing for high-density board designs. This device is commonly used where temporary storage of data is needed before processing or transfer to another location, such as in data acquisition systems and control systems.
