Detailed Pin Configuration

The SN74LVTH162373KR has a total of 48 pins, which are divided into four groups:

1. Data Inputs (A1-A16): These pins receive the input data bits.
2. Data Outputs (B1-B16): These pins provide the output data bits.
3. Control Inputs (G, OE): The G pin is used to enable/disable the latch operation, while the OE pin controls the output enable function.
4. Power and Ground (VCC, GND): These pins provide the power supply and ground connections.

Functional Features

• Transparent Latch: The SN74LVTH162373KR allows data to pass through when the latch is enabled, providing real-time data storage and transfer.
• 3-State Outputs: The 3-state outputs allow multiple devices to share the same bus, reducing the number of required pins and simplifying system design.
• High-Speed Operation: With a propagation delay time of only 4.5ns, this IC ensures efficient data transfer in high-speed applications.
• Low-Voltage Operation: The LVTH logic family allows operation at lower supply voltages, reducing power consumption and heat generation.

Advantages and Disadvantages

Advantages

• High-speed operation enables fast data transfer.
• Low-voltage operation reduces power consumption.
• 3-state outputs allow for bus sharing and simplified system design.

Disadvantages

• Limited to 16-bit data storage and transfer.
• Requires external control signals for latch and output enable functions.

Working Principles

The SN74LVTH162373KR operates based on the principles of transparent latching and 3-state outputs. When the latch is enabled (G = HIGH), the input data is transferred to the outputs in real-time. The output enable (OE) signal controls whether the output drivers are active or in a high-impedance state. This allows multiple devices to share the same bus without interfering with each other's signals.

Detailed Application Field Plans

The SN74LVTH162373KR finds applications in various electronic systems that require reliable and efficient data storage and transfer. Some potential application fields include:

1. Microprocessors and Microcontrollers: Used for interfacing with memory units, peripherals, and other devices.
2. Communication Systems: Facilitates data transmission between different components in communication networks.
3. Data Acquisition Systems: Enables the capture and transfer of analog and digital data from sensors and other sources.
4. Industrial Automation: Supports data exchange between control units, sensors, and actuators in automated systems.
5. Automotive Electronics: Used in vehicle control modules, infotainment systems, and communication interfaces.
