The 74ACQ373 is an octal transparent latch with 3-state outputs manufactured by Fairchild/ON Semiconductor. This device belongs to the ACQ (Advanced CMOS Quiet) logic family, known for its low noise characteristics and high speed. It's used for temporary data storage and is often found in memory systems, data acquisition, and bus interfacing applications.

Applications

• Memory systems: Acting as a temporary data buffer between the memory and the processor.
• Data acquisition systems: Storing data from sensors or other input devices.
• Bus interfacing: Providing a latched interface between different buses or systems.
• Address latching: Capturing address signals for memory access.
• Microprocessor systems: Holding data while the processor performs other operations.

Features

• High speed operation: Typical propagation delay of 5 ns.
• Low noise: Reduced ground bounce and noise generation.
• Transparent latch: Data passes through the latch when the enable input is high.
• 3-state outputs: Allows the outputs to be disabled, effectively disconnecting the device from the bus.
• Output drive capability: IO = 24 mA.

Benefits

• Improved system performance due to high-speed operation.
• Reduced noise, leading to increased system reliability and stability.
• Flexibility in data storage due to transparent latch operation.
• Easy system integration due to 3-state outputs.
• High fan-out capability, allowing the device to drive multiple loads.

The 74ACQ373 offers a combination of high speed, low noise, and flexible data storage capabilities. Its transparent latch function allows data to pass through when enabled, while its 3-state outputs enable easy bus interfacing. The device's high output drive capability makes it suitable for driving heavily loaded buses and transmission lines. It is well-suited for applications where data must be temporarily stored and accessed quickly with minimal noise interference.
