Description

The 74HC574 is a high-speed CMOS octal D-type flip-flop IC with tri-state outputs. It features eight D-type flip-flops that can be individually controlled and provide output states of high, low, or high-impedance (floating). This IC is designed for use in data storage and transfer applications where data needs to be clocked in and selectively driven onto a data bus or other digital lines.

Features

  • Octal D-type flip-flops: Eight independent flip-flops for data storage and transfer.
  • Tri-state outputs: Outputs can be high, low, or in a high-impedance state for flexible bus interfacing.
  • Clocked data entry: Data is entered into the flip-flops on the rising edge of the clock signal.
  • Asynchronous clear and preset: Allows for immediate clearing or presetting of flip-flops independent of the clock.
  • Wide operating voltage range: Operates from 2V to 6V.
  • High-speed performance: Provides fast switching with low propagation delay.
  • Low power consumption: Efficient power usage due to CMOS technology.
  • Standard CMOS logic levels: Compatible with both CMOS and TTL logic levels.
