Functional Features

• Octal transparent D-type latches with 3-state outputs
• High-speed operation
• Low-power consumption
• CMOS logic compatibility
• Non-inverting outputs
• 3-state outputs for bus-oriented applications

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Low-power consumption helps conserve energy. - CMOS logic compatibility ensures compatibility with a wide range of devices. - 3-state outputs enable bus-oriented applications.

Disadvantages: - Limited voltage supply range (4.5V to 5.5V). - Propagation delay time may affect timing-sensitive applications.

Working Principles

The SN74AHCT373PW operates as an octal transparent latch. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7) on the rising edge of the clock input (CLK). The output enable (OE) input controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74AHCT373PW can be used in various applications, including:

1. Data storage and transfer in microcontrollers and microprocessors.
2. Address and data bus interfacing in computer systems.
3. Memory address decoding and control signal generation.
4. General-purpose digital logic applications.
