SNJ54ABT374FK: Octal Edge-Triggered D-Type Flip-Flops

The SNJ54ABT374FK is a high-performance, octal edge-triggered D-type flip-flop integrated circuit (IC) designed and manufactured by Texas Instruments (TI). This IC is part of the ABT family, which is known for its advanced BiCMOS technology, combining the high speed of bipolar with the low power of CMOS. The SNJ54ABT374FK is specifically crafted to address the needs of high-speed memory buffering and data storage applications.

Each flip-flop in the SNJ54ABT374FK has a 3-state output, which enables the device to be used in bus-oriented systems. The 3-state outputs allow the flip-flops to either drive the data bus or be disconnected from it, providing a high degree of flexibility in multiplexed data lines and bus management.

The device operates on a 4.5V to 5.5V supply voltage range, making it compatible with many standard logic levels and providing a margin for a variety of system voltages. Its edge-triggered design ensures that data is captured on the rising edge of the clock signal, which is essential for synchronous operations and helps to maintain data integrity across all eight channels.

Key features of the SNJ54ABT374FK include:

• Eight edge-triggered D-type flip-flops with individual D inputs and Q outputs.
• 3-state outputs for bus-oriented applications.
• Operates from a 4.5V to 5.5V V<sub>CC supply range.
• Input and output are designed for low-voltage operation (5V).
• Edge-triggered from a low-to-high transition of the clock pulse.
• High drive capability with 24mA output drive at 5V.
• Supports live insertion and withdrawal (partial power-down).
• Available in military-grade specifications to ensure reliability under harsh conditions.

The SNJ54ABT374FK is housed in a ceramic flat package (FK) which provides excellent thermal performance and is suitable for military and aerospace applications that demand high levels of reliability and robustness. The package is also conducive to high-speed signal processing due to its low parasitic inductance and capacitance.

TI's SNJ54ABT374FK is an ideal solution for designers who require a reliable and high-speed octal flip-flop for their digital systems. Its features make it highly suitable for applications such as temporary data storage, data synchronization, and act as an interface between mismatched clock domains.
