STMicroelectronics 74LVQ573 Octal D-Type Latch
The 74LVQ573 is a high-speed CMOS octal D-type transparent latch manufactured by STMicroelectronics, designed for 2V to 3.6V V<sub>CC operation. This advanced technology device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory, making it an excellent choice for a wide range of applications in the telecommunications, computing, and industrial sectors.
Key Features
- High-Speed Performance: The 74LVQ573 operates at a high speed with a typical propagation delay time significantly lower than other comparable CMOS devices, ensuring swift data handling in critical applications.
- Low Power Consumption: Designed with power efficiency in mind, it features a low power dissipation, making it ideal for battery-operated and power-sensitive applications.
- Octal D-Type Latches: It contains eight latches with 3-state outputs for bus-oriented applications. The 3-state outputs can be used to interface with bus lines in a bidirectional manner.
- Transparent Latches: The latches are transparent, meaning that when the Latch Enable (LE) input is high, the Q outputs follow the data (D) inputs.
- Output Control: The Output Enable (OE) input, when low, places the eight outputs in a normal operational mode; when high, the outputs are in a high impedance state, thus ensuring that the outputs are effectively disconnected to allow for bus sharing.
Applications
The versatility of the 74LVQ573 makes it suitable for a multitude of applications, including:
- Buffer registers for data management
- I/O ports in microcontroller-based systems
- Bus drivers for data transfer and communication
- Memory address latching
- Industrial control systems
- Telecommunications infrastructure
