Product Overview: 74ABT574A Octal D-Type Flip-Flop by NXP
The 74ABT574A is a high-performance, octal D-type flip-flop with 3-state outputs from NXP Semiconductors. This integrated circuit is designed to provide a high-speed, low-power solution for storage and transfer of 8-bit data. With its advanced BiCMOS technology, the 74ABT574A offers both high-speed operation and reduced power consumption, making it an ideal choice for interfacing with bus-oriented systems.
The device features eight edge-triggered D-type flip-flops with individual D inputs and O outputs. The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously. When the clock input is at a high state, the Q outputs will respond to the data inputs. Conversely, when the master reset is active, all outputs are forced low, regardless of other inputs.
One of the key features of the 74ABT574A is its 3-state output control, which allows for connection to a bus-oriented system. The output enable (OE) input can disable the device, thereby placing the outputs in a high-impedance state. This ensures that the flip-flops can be integrated smoothly within systems that require shared data lines without causing contention.
- Supply Voltage Range: The device operates at a nominal supply voltage of 5V, making it compatible with TTL power levels while providing improved speed and drive capabilities.
- High-Speed Operation: The 74ABT574A is capable of operating at high speeds, with a typical clock frequency of up to 200MHz, which is essential for high-performance data processing and communication applications.
- Low Power Dissipation: It features a reduced power consumption profile, which is critical for energy-sensitive applications.
- Improved Output Drive: The device can source or sink 50 mA of output drive, providing robust signal integrity even in demanding environments.
- ESD Protection: The 74ABT574A includes protection against electrostatic discharge, ensuring the device's reliability and longevity in various operating conditions.
The NXP 74ABT574A is packaged in a 20-pin plastic SOIC or SSOP, which is suitable for surface-mounted technology (SMT). This makes it an excellent choice for compact designs where space is at a premium. With its robust feature set and proven reliability, the 74ABT574A from NXP is an essential component for designers who require a high-speed, low-power octal flip-flop for their digital applications.
