STMicroelectronics 74ACT373 Octal Transparent Latch

The 74ACT373 from STMicroelectronics is an advanced high-speed CMOS Octal Transparent Latch with 3-state outputs. This integrated circuit is designed to be used in high-performance memory storing and data management applications where low power consumption and high efficiency are of paramount importance. The device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory.

Key Features

• High-Speed Operation: The 74ACT373 operates at high speeds, making it ideal for systems that require fast data storage and retrieval.
• Low Power Dissipation: It has been optimized for low power consumption, which is critical for battery-operated and power-sensitive applications.
• Octal D-Type Latch: The device features eight latches with 3-state outputs, which can be used independently or combined for larger data storage requirements.
• Transparent Latch: The latches are transparent, meaning that when the latch enable (LE) input is high, the Q outputs will follow the data (D) inputs.
• Output Control: The Output Enable (OE) bar input can be used to place the eight outputs in either a normal logic state or a high-impedance state, which is useful when interfacing with bus lines in a multi-master environment.
• Bus-Compatible Outputs: The 3-state outputs are designed to interface directly with system buses, providing both high-speed data transfer and bus isolation when required.

Applications

The 74ACT373 is versatile and can be used in a variety of applications, including:

• Memory storage and buffers
• Bus drivers
• Data management systems
• Computers and computer peripherals
