Functional Features

The SN74ABT574ADW is a D-type transparent latch with 3-state outputs. It has the following functional features:

• High-speed operation
• Low-power consumption
• 3-state outputs for bus-oriented applications
• Transparent latch for easy data transfer
• Master reset for initialization

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick data processing - Low-power consumption helps in reducing energy usage - 3-state outputs enable efficient bus-oriented applications - Transparent latch simplifies data transfer - Master reset provides a convenient way to initialize the latch

Disadvantages: - Limited supply voltage range (4.5V to 5.5V) - Narrow operating temperature range (-40°C to +85°C)

Working Principles

The SN74ABT574ADW operates as a D-type transparent latch with 3-state outputs. When the clock pulse (CP) is high, the latch transfers the data from the input pins (D0-D7) to the output pins (Q0-Q6). The output enable (OE) pin controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

The master reset (MR) pin initializes the latch by setting all outputs to a low logic level when activated. This feature is useful for system initialization or error recovery.
