Functional Features

The SN74F373DBR offers the following functional features:

• Octal transparent latch with 3-state outputs
• Individual latch enable for each latch
• Output enable to put the outputs in a high-impedance state
• TTL-compatible inputs for easy integration into existing systems
• High-speed operation for efficient data transfer

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick data processing - Wide operating voltage range makes it compatible with various systems - 3-state outputs enable bus-oriented applications - TTL-compatible inputs simplify integration

Disadvantages: - Limited output current may not be suitable for high-power applications - Propagation delay time may affect real-time data processing

Working Principles

The SN74F373DBR operates by latching the input data when the latch enable (LE) signal is active. The clock input (CLK) determines when the data is transferred to the outputs. The output enable (OE) signal controls whether the outputs are active or in a high-impedance state.
