Product Overview: 74LVT573 Octal D-Type Transparent Latch from NXP

The 74LVT573 from NXP Semiconductors is an octal D-type transparent latch that is part of the LVT family, which offers low-voltage, high-speed operation compatible with LVTTL signal levels. This integrated circuit is designed to provide storage and interface capabilities for 8-bit wide data paths within your digital systems. With its robust design, it is suitable for a wide range of applications, including computers, servers, networking, and industrial equipment.

Key Features

• Logic Type: The 74LVT573 is an octal D-type transparent latch, which means it has eight latches with D-type flip-flops that can store data when the latch enable (LE) signal is high.
• High-Speed Operation: This device operates at a high speed with a typical propagation delay of only a few nanoseconds, facilitating quick data transfer and processing.
• Low-Voltage Operation: It is designed to operate at a nominal supply voltage of 3.3V, which is ideal for low-voltage applications and helps in reducing overall power consumption.
• 3-State Outputs: The octal latches feature 3-state outputs to allow for connection to a bus or other data lines without interfering with other devices.
• Bus-Hold Data Inputs: The device includes bus-hold circuitry on all data inputs, which eliminates the need for external pull-up or pull-down resistors and ensures that the inputs retain last known states when left floating.
• Compatibility: The 74LVT573 is compatible with LVTTL and LVCMOS technologies and can interface with 5V I/O signals without additional components, making it highly versatile.
• Package Options: It is available in various package types, including TSSOP, SO, and SSOP, providing flexibility for different design requirements and space constraints.

Applications

The 74LVT573 is well-suited for a variety of applications where data needs to be temporarily stored and accessed. Its use cases include:

• Temporary data storage in computer and server systems
• Interface for peripheral devices in computing
• Data buffering in networking equipment
• Industrial control systems requiring high-speed data latching

With its combination of high-speed operation, low-power consumption, and flexible interfacing capabilities, the NXP 74LVT573 is a reliable and efficient choice for designers looking to optimize their digital systems.
