Disadvantages: - Limited output drive capability may restrict use in high-current applications - Requires external control signals for proper operation

Working Principles

The SN74ACT573NE4 operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7) in real-time. The outputs can be enabled or disabled using the output enable (OE) input. When OE is low, the outputs are active and reflect the input data. When OE is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74ACT573NE4 is widely used in various digital systems where data storage and transfer are required. Some application fields include:

  1. Microprocessors and microcontrollers
  2. Data communication systems
