Functional Features

• Latch Function: The 74ACT373SCX can store data when the latch enable (LE) input is high and transparently transfer the stored data to the outputs when the latch enable is low.
• Output Enable: The output enable (OE) input allows the outputs to be in a high-impedance state, enabling multiple devices to share a common bus without interference.
• 3-State Outputs: The 3-state outputs provide flexibility in controlling the flow of data within a digital system.

Advantages and Disadvantages

Advantages: - High-speed operation - Octal latch with 3-state outputs - Suitable for various digital applications - Easy integration into existing systems

Disadvantages: - Limited voltage range (2V to 6V) - Propagation delay may affect timing-sensitive applications

Working Principles

The 74ACT373SCX operates based on the principle of transparent latching. When the latch enable (LE) input is high, the data inputs (D0-D7) are stored in the internal latches. The stored data is then transferred to the outputs (Q0-Q7) when the latch enable is low. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The 74ACT373SCX is widely used in various digital systems and applications, including but not limited to: - Microprocessors and microcontrollers - Memory systems - Data communication systems - Industrial automation - Automotive electronics
