Specifications

The 74ALVCH16373DL,118 is a high-performance, low-voltage, 16-bit transparent latch designed for data storage and transfer applications. It operates at a voltage range of 1.65V to 3.6V, making it suitable for use in various electronic devices.

Detailed Pin Configuration

The IC has a total of 48 pins, which are distributed as follows:

• Pins 1 to 24: Inputs/Outputs (I/O) for the A-side of the latch
• Pins 25 to 48: I/O for the B-side of the latch

Functional Features

• Transparent Latching: The IC allows data to be latched transparently when the latch enable (LE) input is high.
• 3-State Outputs: The outputs can be put into a high-impedance state by setting the output enable (OE) input to high.
• Wide Bus: The latch supports a 16-bit wide bus, enabling the storage and transfer of large amounts of data.

Advantages and Disadvantages

Advantages:

• High-Speed Operation: The IC offers fast data storage and transfer capabilities, making it suitable for time-critical applications.
• Low-Voltage Operation: With its low-voltage range, the IC is compatible with modern low-power electronic devices.
• 3-State Outputs: The ability to put the outputs in a high-impedance state allows for easy integration with other components.

Disadvantages:

• Limited Voltage Range: The IC operates within a specific voltage range, which may restrict its use in certain applications.
• Package Size: The TSSOP package may require additional space on the circuit board compared to smaller package options.

Working Principles

The 74ALVCH16373DL,118 is based on transparent latch technology. When the latch enable (LE) input is high, the data inputs are transferred to the outputs. The latch remains transparent as long as LE is high. The output enable (OE) input controls the state of the outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The 74ALVCH16373DL,118 can be used in various applications, including:

1. Data Storage Systems: The IC can be utilized in memory modules and storage devices where fast and reliable data transfer is required.
2. Communication Equipment: It can be employed in networking devices, routers, and switches to handle data transmission between different components.
3. Industrial Control Systems: The IC can be integrated into control systems to store and transfer data between sensors, actuators, and controllers.
