Detailed Pin Configuration

The SN74ALVCH16373KR has a total of 48 pins, which are divided into various functional groups:

• Data Inputs (D0-D15): These pins are used to input the 16-bit data that needs to be stored or transferred.
• Latch Enable (LE): This pin enables or disables the latch function.
• Output Enable (OE): When this pin is low, the outputs are in the high-impedance state.
• Clock (CLK): The rising edge of the clock signal latches the data inputs into the latch.
• 3-State Outputs (Q0-Q15): These pins provide the stored or transferred data.

Functional Features

• High-speed operation allows for efficient data transfer.
• Low-voltage operation makes it suitable for battery-powered devices.
• 3-state outputs enable easy bus sharing between multiple devices.
• Transparent latch design allows real-time data updates.
• Schmitt-trigger inputs provide noise immunity.

Advantages and Disadvantages

Advantages: - High-speed operation enables fast data transfer. - Low-voltage operation extends battery life in portable devices. - 3-state outputs facilitate bus sharing between multiple devices. - Transparent latch design allows real-time data updates.

Disadvantages: - Limited voltage range may not be suitable for all applications. - The package size may require additional space on the circuit board.

Working Principles

The SN74ALVCH16373KR is a transparent latch, which means that the data inputs are directly transferred to the outputs when the latch enable (LE) signal is high. The clock signal (CLK) controls when the data inputs are latched into the latch. When the output enable (OE) signal is low, the outputs are active and reflect the stored or transferred data. When OE is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74ALVCH16373KR can be used in various applications, including:

1. Data storage and transfer in microprocessors and microcontrollers.
2. Address and data bus interfacing in digital systems.
3. Memory modules and cache systems.
4. Communication systems and networking equipment.
5. Industrial automation and control systems.
