  • TTL-compatible inputs and outputs
  • High-speed operation for efficient data transfer
  • Suitable for bus-oriented applications

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer - 3-state outputs enable bus sharing among multiple devices - Eight latches in a single package provide compact design options - TTL-compatible inputs and outputs ensure compatibility with existing systems

Disadvantages: - Limited to a maximum clock frequency of 100MHz - Requires careful consideration of timing requirements in complex systems

Working Principles

The SN74ACT373NG4 operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data on the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74ACT373NG4 is commonly used in various applications, including: - Data buses in microprocessors and microcontrollers - Memory address and data storage systems - Input/output (I/O) interfaces - Communication systems - Control systems
