Functional Features

• Octal D-type transparent latch with 3-state outputs
• Latch enable (LE) input for storing data
• Clock (CLK) input for transferring data to the outputs
• Output enable (OE) input for enabling/disabling the outputs
• 3-state outputs allow multiple devices to share a common bus

Advantages and Disadvantages

Advantages: - High-speed operation - Wide operating voltage range - 3-state outputs provide flexibility in bus sharing applications

Disadvantages: - Limited number of inputs and outputs - Not suitable for applications requiring a large number of latches

Working Principles

The SN74ACT563N is a latch IC that can store and transfer digital data. When the latch enable (LE) input is high, the data on the data inputs (D0-D7) is stored in the latch. The clock (CLK) input is used to transfer the stored data to the outputs (Q0-Q7). The output enable (OE) input controls whether the outputs are enabled or disabled.

Detailed Application Field Plans

The SN74ACT563N is commonly used in various digital logic applications, including:

1. Data storage and transfer in microcontrollers and microprocessors.
2. Address decoding in memory systems.
3. Bus interfacing in communication systems.
4. Control signal generation in industrial automation.
5. State machine implementation in digital circuits.

Detailed and Complete Alternative Models

Some alternative models to the SN74ACT563N include:

1. SN74HC563N: Octal D-type transparent latch with 3-state outputs, compatible with 5V supply voltage.
2. CD74ACT563E: Octal transparent latch with 3-state outputs, operates at a wider temperature range (-55°C to +125°C).
3. MC74ACT563DW: Octal D-type transparent latch with 3-state outputs, available in surface mount package.
