Additional Details

The IDT54FCT374DB features eight D-type flip-flops, each with its own data input and a common clock and output enable. The flip-flops are positive-edge triggered, meaning that data is latched on the rising edge of the clock signal. The 3-state outputs allow the device to be connected directly to a bus, enabling multiple devices to share the same data lines. When the output enable is deasserted, the outputs are placed in a high-impedance state, preventing them from interfering with other devices on the bus.

The device also includes a direct clear input, which asynchronously resets all flip-flops to a low state. The TTL-compatible inputs and outputs simplify interfacing with other logic devices. The IDT54FCT374DB is available in various package options, including ceramic DIP and surface-mount packages.

Key Specifications: Supply voltage: 4.75V to 5.25V, Operating temperature: -55°C to +125°C. Output drive capability supports driving highly loaded buses.
