Product Overview: 74LVT573D-T from NXP

The 74LVT573D-T is a high-performance, low-voltage octal transparent D-type latch with 3-state outputs, designed by the renowned semiconductor manufacturer, NXP. This product is part of the LVT family, which is known for its low-voltage operation and high-speed performance. It is particularly suitable for interfacing with 3.3V systems in a wide range of industrial, commercial, and computing applications where high data throughput is required.

Key Features

• Octal D-Type Latches: The device contains eight latches with D-type flip-flops that capture the state of their inputs when the latch-enable (LE) input is high, holding the data when LE is low.
• 3-State Outputs: This feature allows for connection to a bus-oriented system. The outputs can be put in a high-impedance state, effectively disconnecting them from the bus.
• Low-Voltage Operation: The 74LVT573D-T operates at a nominal voltage of 3.3V, making it compatible with other low-voltage logic families.
• High-Speed Performance: The device provides a high-speed data flow with a minimal propagation delay, essential for high-performance systems.
• Live Insertion and Extraction: The 74LVT573D-T supports live insertion and extraction, reducing system downtime during maintenance and upgrades.
• Power-Off High-Impedance Inputs and Outputs: This feature ensures that the device remains in a safe state when powered off.
• ESD Protection: Enhanced electrostatic discharge (ESD) protection is built-in to prevent damage from static electricity and handling.
