Product Overview: MC74VHCT574ADW from ON Semiconductor

The MC74VHCT574ADW is a high-performance, octal D-type flip-flop with 3-state outputs from ON Semiconductor. This integrated circuit is designed to interface directly with high-speed memory systems and is fabricated with silicon gate CMOS technology. It combines the low power consumption of CMOS with the speed and drive capabilities of bipolar transistors, offering a robust and efficient solution for digital data storage and transfer.

The device features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. These outputs can be placed in either a high impedance state or a logic high/low state, allowing for bidirectional interfacing with bus-oriented systems. The flip-flops will store the state of their individual D-inputs that meet the setup and hold time requirements on the LOW-to-HIGH clock (CLK) transition.

The MC74VHCT574ADW operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL levels while maintaining the low power consumption of CMOS technology. It also features a high noise immunity characteristic of CMOS devices. The input pins are designed to withstand -0.5V to 7.0V, allowing for additional protection during installation and operation.

The OE (Output Enable) input controls the 3-state outputs and ensures that the outputs appear either high impedance or at a valid logic level. When OE is high, the outputs are in a high impedance state, which is particularly useful during power-up or power-down sequences to avoid any erroneous data transmission.

The MC74VHCT574ADW comes in a 20-pin SOIC package, providing a compact footprint for space-constrained applications. Its operating temperature range spans from -55°C to +125°C, ensuring reliability and performance across various environmental conditions. This device is ideal for applications that require high-speed data capture, data buffering, and bus interfacing in computing, telecommunications, and industrial markets.

In summary, the MC74VHCT574ADW from ON Semiconductor is a versatile and reliable choice for designers looking for a high-speed octal D-type flip-flop with the benefits of CMOS technology and compatibility with TTL signal levels.
