74AC574MTR Octal D-Type Flip-Flop from STMicroelectronics
The 74AC574MTR is a high-speed, octal D-type flip-flop integrated circuit from STMicroelectronics, designed for use in applications requiring the storage and retrieval of data. It consists of eight edge-triggered flip-flops with individual D-type inputs and three-state outputs. This device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
The 74AC574MTR offers a wide operating voltage range of 2V to 6V, providing compatibility with TTL power levels while maintaining CMOS low power consumption. It features a high-speed throughput, with a typical clock frequency of 150 MHz at 5V, making it a robust choice for high-performance systems.
Each flip-flop has a separate Data (D) input, Clock (CLK) input, and a complementary Output (Q) and Output Inverted (Q̅) to provide true and complementary outputs. The data on the D input is accepted by the flip-flops on the rising edge of the clock pulse, and the data is available at the Q outputs in the high-impedance state when the Output Enable (OE̅) is high.
The 74AC574MTR is available in a surface-mount package, specifically the TSSOP20 (Thin Shrink Small Outline Package), which is suitable for automated assembly processes and space-constrained applications. The device also features a latch-up performance that exceeds 500mA on all pins, providing additional reliability and robustness in complex electronic systems.
With its fast switching speeds and low power consumption, the 74AC574MTR is optimized for use in a variety of digital applications such as personal computers, communication devices, and high-speed data processing systems. Its ability to interface with both CMOS and TTL logic levels makes it a versatile choice for mixed-technology environments.
In summary, the 74AC574MTR from STMicroelectronics is a high-quality, high-speed octal flip-flop that offers designers flexibility, performance, and reliability for a wide array of digital applications.
