SN74ABT374A Octal Edge-Triggered D-Type Flip-Flops

The SN74ABT374A is a high-performance, octal edge-triggered D-type flip-flop integrated circuit from Texas Instruments. Designed for 5V systems, it features eight edge-triggered D-type flip-flops with 3-state outputs, making it ideal for bus-oriented applications. The 3-state outputs can connect directly to and drive data bus lines or buffer memory address registers.

Each flip-flop is designed with a clear (CLR) and clock (CLK) input. The flip-flops transition on the rising edge of the clock while the CLR input is used to simultaneously clear all flip-flops when taken low. This synchronous clear allows the system to reset the flip-flops quickly and uniformly, which is essential for maintaining data integrity during power-up or when a quick system reset is required.

The SN74ABT374A is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions. The device comes in a variety of packages, including the widely used 20-pin DIP (Dual In-line Package), providing compatibility with standard breadboards, sockets, and PCB layouts.

Key features of the SN74ABT374A include:

• Eight edge-triggered D-type flip-flops with 3-state outputs
• Output capability: Bus driver
• ICC category: Flip-flops
• Designed specifically for driving highly capacitive or relatively low-impedance loads
• High-impedance state during power up and power down
• High drive outputs (-32-mA IOH, 64-mA IOL)

With its robust design and high-speed performance, the SN74ABT374A is an excellent choice for a wide array of applications, including memory address registers, data storage, and data transfer systems. Its ability to directly drive data buses and compatibility with 5V systems makes it a versatile component for both legacy and new designs.
