Product Description

The 74AHC374D is designed for the storage and transfer of eight bits of data. Each flip-flop has a 3-state output, which can be used in bus-oriented applications where the ability to disconnect the output from the bus is required. The device features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs load and reset (clear) all flip-flops simultaneously.

The setup time is short enough to allow for high-speed operation, which is essential in fast data handling and processing systems. The device operates over a broad voltage range from 2.0V to 5.5V and offers symmetrical output impedance, ensuring high noise immunity and reduced power consumption. The 74AHC374D is suitable for a wide range of applications including buffers, registers, data storage, and multiplexed displays.
