Functional Features

The SN74AHC573N is an octal transparent latch with 3-state outputs. It allows data to be latched and stored when the latch enable (LE) input is high. The latch is transparent when the output enable (OE) input is low, allowing the data inputs to pass through to the outputs. When the OE input is high, the outputs are in a high-impedance state.

Advantages and Disadvantages

Advantages

• High-speed operation
• 3-state outputs for bus-oriented applications
• Transparent latch for easy data storage

Disadvantages

• Limited voltage range (2 V to 5.5 V)
• Propagation delay of 7 ns

Working Principles

The SN74AHC573N operates by using the latch enable (LE) input to control the storage of data. When LE is high, the data inputs (D0-D7) are latched and stored in the internal registers. The output enable (OE) input controls the output state. When OE is low, the outputs (Q0-Q7) reflect the current state of the data inputs. When OE is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74AHC573N is commonly used in various applications, including:

1. Microprocessor systems
2. Data storage systems
3. Communication systems
4. Industrial automation
5. Automotive electronics

Detailed and Complete Alternative Models

Some alternative models that can be considered as alternatives to the SN74AHC573N are:
