Key Features

  • Octal 8-bit D flip-flop with 3-state outputs enabling bus isolation and high-impedance drive
  • High-speed operation up to 150 MHz with LVC low-voltage CMOS technology
  • Wide supply voltage range of 1.65V to 3.3V for mixed-voltage system compatibility
  • Active-low output enable for easy bus control in unidirectional data buffering applications

Applications

The SN74LVC574ANSR is used as a data register and bus driver in microprocessor and FPGA interface designs requiring latched 8-bit data paths. It is commonly deployed in memory address latching, parallel data buffering, and I/O port expansion circuits in embedded systems. Its 3-state outputs allow multiple devices to share a common data bus without signal contention.
