• High-speed operation, suitable for applications requiring fast data transfer
• Logic level translation capability allows interfacing between different voltage domains
• Output enable pin (OE) provides control over the output state
• Clock pulse input (CP) triggers the flip-flop to latch the input data

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer - Logic level translation simplifies interfacing between different voltage levels - 3-state outputs allow multiple devices to share a common bus - Compact PDIP package facilitates easy integration into various circuit designs

Disadvantages: - Limited supply voltage range restricts compatibility with certain systems - Propagation delay time may affect timing-sensitive applications - PDIP package may not be suitable for space-constrained designs

Working Principles

The SN74AS533AN operates as an octal D-type flip-flop with non-inverting outputs. The flip-flop stores the input data on the rising edge of the clock pulse. The stored data is then available at the respective output pins. The output enable pin controls the output state, allowing the device to be tri-stated when necessary.
