Product Overview: 74LV573DB - Octal D-type Transparent Latch from NXP

The 74LV573DB is a high-performance, octal D-type transparent latch designed and manufactured by NXP Semiconductors. This integrated circuit is part of the 74LV family, which operates on a low-voltage platform, making it suitable for battery-operated and portable devices where power efficiency is critical. The device features eight latches with 3-state outputs for bus-oriented applications.

Key Features

• Logic Family: The 74LV573DB operates within the 74LV logic family, known for its low-voltage operation and compatibility with TTL levels.
• Supply Voltage Range: It has a broad supply voltage range of 2.0V to 5.5V, which allows for flexible integration into various system voltage levels.
• High-Speed Performance: This latch offers high-speed performance with a typical propagation delay of only 6.5ns, ensuring quick response times in critical applications.
• Transparent Latches: The transparent nature of the latches means that while the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs.
• 3-State Outputs: The octal latch features 3-state outputs, which can be set to a high-impedance state, effectively disconnecting the output from the circuit, a feature beneficial for bus systems.
• Output Capability: The device can drive 15 LSTTL loads, providing ample output capability for interfacing with other logic families.
• Wide Operating Temperature: The 74LV573DB is designed to operate over a wide temperature range from -40°C to +125°C, making it suitable for industrial applications.
