74LS574 Octal Edge Triggered D Flip-Flop IC

The 74LS574 comes as a part of the 74XXYY IC series. The 74LS574 designed as a high-speed, low-power Octal D-type Flip-Flop featuring separate D-type inputs for every flip-flop. And 3-state outputs for bus-oriented applications. The two sections of the IC  controlled independently by the buffered Clock (CP) and Output Enable (OE) control gates provided to all flip-flops in the IC.

The register is fully edge-triggered. The data presented to the D inputs stored within the flip-flops on the LOW-to-HIGH Clock (CP) transition. The state of every D input, one setup time before the Low-to-High clock transitiontransferred to the corresponding flip-flop’s Q output. The 3-State output buffers drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. Moreover, the active Low Output Enable (OE) controls all eight 3-State buffers independently of the latch operation. Under the condition, when OE is Low, the latched or transparent data appears at the outputs. When OE is High, the outputs are during a high impedance “off” state, which suggests they’re going to neither drive nor load the bus.

A D-type latch/flip-flop with two stable states that is designed as a timed latch. A D-type latch has a one-clock-cycle delay in its input. Delay circuits are frequently produced by cascading multiple D-type flip-flops. This was then used in a variety of applications, such as digital television systems. A D flip-flop, sometimes known as a delay flip-flop, is a D-type flip-flop.

Applications

• Function  as a digital building block for a wide variety of temporary data storage & processing devices such as SRAMs & DRAMs etc.

• Also Useful as Input or Output Port for Microprocessors
