74LVC574A - Octal D-type flip-flop

General Description

The 74LVC574A is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications.

A clock (CP) and an Output Enable (OE) input are common to all flip-flops.

Key Features

  • 5 V tolerant inputs for interfacing with 5 V logic.
  • Supply voltage range from 1.2 V to 3.6 V.
  • CMOS low power consumption.
  • Direct interface with TTL levels.
  • High-impedance when VCC = 0 V.
  • 8-bit positive edge-triggered register.
  • Independent register and 3-state buffer operation.
  • Flow-through pin-out architecture.
  • Complies with JEDEC standard:.
  • JESD8-7A (1.65 V to 1.95 V).
  • JESD8-5A (2.3 V to 2.7 V).
  • JESD8-C/JESD36 (2.7 V to 3.6 V).
  • E.

74LVC574A Octal D-type flip-flop with 5 V tolerant inputs/outputs; positive edge-trigger; 3-state Rev. 5 — 18 December 2012 Product data sheet 1. General description The 74LVC574A is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock (CP) and an Output Enable (OE) input are common to all flip-flops. The eight flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW to HIGH CP transition. When OE is LOW, the contents of the eight flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Inputs can be driven from either 3.
