CD74HCT374M Octal D-Type Flip-Flop by Texas Instruments

The CD74HCT374M is a high-speed CMOS Logic Octal D-Type Flip-Flop with 3-state outputs manufactured by Texas Instruments. This integrated circuit is designed for use in applications requiring high-performance and low-power consumption. It is part of the HCT family, which is compatible with TTL logic levels, making it suitable for interfacing with standard TTL integrated circuits.

This device features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The flip-flops transition on the positive-going edge of the clock pulse, and the arrangement allows for synchronous state changes in the data outputs when the clock input is provided. A clear input is also provided, which when taken low, simultaneously clears all flip-flops to the low state.

The CD74HCT374M has additional 3-state output control inputs (OE), which can be used to place the eight outputs in a high-impedance state. This feature is particularly useful for interfacing with bus-oriented systems where it is necessary to effectively disconnect the outputs from the bus without disrupting the bus line.

The device is packaged in a standard SOIC-20 package, making it compact and suitable for surface-mount technology (SMT). The CD74HCT374M operates over a broad voltage range of 4.5V to 5.5V and offers a balanced propagation delay and transition times, providing reliable and fast performance in your digital logic applications.

Key features of the CD74HCT374M include:

• Eight D-type flip-flops in a single package
• 3-state outputs for bus interfacing
• Compatible with TTL logic levels
• Edge-triggered from a positive-going clock transition
• Wide operating voltage range of 4.5V to 5.5V
• Standard SOIC-20 package for easy integration

Whether you are designing data storage, buffer registers, or bus-oriented systems, the CD74HCT374M from Texas Instruments provides a reliable and efficient solution for your digital logic needs.
