The SN74ALVCH16973DLR from Texas Instruments is a high-performance, 16-bit transparent D-type latch with 3-state outputs. This integrated circuit is part of the advanced low-voltage CMOS (ALVC) family and is designed to offer both high drive capability and low static power consumption. With its wide operating voltage range and edge-rate control circuitry, this latch is ideal for use in a variety of high-speed and power-sensitive applications.

Key Features

• Operating Voltage: The device operates at a voltage range of 2.3 V to 3.6 V, making it suitable for interfacing with 3.3 V logic levels while providing a margin for power supply variations.
• High-Speed Operation: It features a typical t<sub>pd of 3.8 ns at 3.3 V, allowing for high-speed data capture and processing.
• Bus-Hold Data Inputs: The latch comes with bus-hold circuitry on all data inputs, which eliminates the need for external pull-up or pull-down resistors and simplifies design.
• Low Power Consumption: The SN74ALVCH16973DLR offers a low ICC of only 4 µA max, contributing to energy-efficient designs.
• 3-State Outputs: These outputs can be placed in a high-impedance state, enabling bidirectional data flow and easy multiplexing.
• Flow-Through Architecture: This design optimizes the PCB layout and reduces signal skew by placing the inputs near the outputs.

Applications

With its robust feature set, the SN74ALVCH16973DLR is perfect for a wide range of applications, including:

• Memory address latching in computing systems
• Interface and bus isolation in telecom and datacom systems
• Buffering and storage in industrial controls
• High-speed data acquisition systems
