Product Overview: 74LV573D from NXP
The 74LV573D is a high-performance, low-voltage Octal D-type transparent latch designed by NXP Semiconductors. This integrated circuit (IC) is part of NXP's 74LV family, which operates at a lower voltage range, making it ideal for battery-operated and portable applications. The device's primary purpose is to hold or "latch" data at its inputs whenever the latch enable (LE) input is high, and pass it through to the outputs when LE is low.
Key Features:
- Voltage Range: The 74LV573D operates at a nominal voltage of 3.3V, which can range from 2.0V to 3.6V, ensuring compatibility with low-voltage systems and providing a power-efficient solution.
- Octal Configuration: It features eight latches, hence the term 'octal', which allows for the simultaneous handling of eight data lines.
- Transparent Latch: When the latch enable (LE) input is high, data at the input pins passes transparently to the outputs. The latches store the input data present one setup time before the LE transition from high to low.
- 3-State Outputs: The 74LV573D includes 3-state outputs which can be put into a high-impedance state, effectively disconnecting the output from the circuit, which is useful for shared data lines and bus-oriented systems.
- Low Power Consumption: Designed for low power consumption, it is suitable for power-sensitive designs.
- Wide Operating Temperature: The device can operate over a broad temperature range, making it versatile for different environmental conditions.
Applications:
The 74LV573D is widely used across various applications due to its versatility and performance. Some common uses include:
- Temporary data storage
- Data buffering for CPUs, computers, and other computing systems
- Interface between mismatched data buses
- Support for systems that require stable data availability during transient conditions
Quality and Reliability:
NXP Semiconductors ensures that the 74LV573D meets stringent quality and reliability standards. The device is thoroughly tested and is designed to maintain functionality over its specified lifespan, even under challenging conditions.
Conclusion:
With its low-voltage operation, transparent latching capability, and 3-state outputs, the 74LV573D from NXP is an excellent choice for designers looking for a reliable and efficient solution for data storage and buffering in their electronic circuits.
