Description

The 74VHC574MX is an eight-bit advanced high-speed CMOS flip-flop with 3-state output, designed using silicon gate CMOS technology. This flip-flop has the same speed of operation as equivalent Bipolar Schottky TTL while consuming low power of CMOS. It features a clock input (CP) and an output enable input (OE) that allows the outputs to be in high impedance state when OE is HIGH.

Specifications and Features

• High Speed: The typical propagation delay time (tPD) is 5.6 ns at VCC = 5V.
• High Noise Immunity: It has a minimum noise immunity of VNIH=VNIL=28% VCC.
• Power Down Protection: Power Down Protection is provided on all inputs.
• Low Noise: It has a typical output noise voltage (VOLP) of 0.6V.
• Low Power Dissipation: It consumes a maximum supply current of 4 µA at TA = 25°C.
• Pin and Function Compatible with 74HC574: It is pin and function compatible with the 74HC574, making it easily integrated into existing designs.

Application Scenarios

The 74VHC574MX can be used in various applications, such as memory registers, address latches, and data storage.
