The TC74AC573F is an octal D-type transparent latch with 3-state outputs manufactured by Toshiba. This device is commonly used for temporary data storage and buffering in digital systems. Its 3-state outputs allow it to be easily connected to a bus system.

Applications

• Data buffering
• Address latching
• Memory address decoding
• Microprocessor systems
• General-purpose logic

Features

• Octal D-type transparent latch
• 3-state outputs
• High-speed operation
• Low power consumption
• Wide operating voltage range
• Fanout capability: 15 LSTTL loads

Benefits

• Temporary data storage: Latches data when the enable input is high and stores the data when the enable input is low.
• Bus compatibility: 3-state outputs allow for easy connection to a shared bus.
• High-speed performance: Suitable for high-speed digital systems.
• Energy efficient: Low power consumption minimizes energy usage in portable devices and other power-sensitive applications.
• Versatile operation: Wide operating voltage range allows the device to be used in various logic systems.

Additional Details

The TC74AC573F is part of the Advanced CMOS (AC) logic family, known for its high speed and low power consumption. The device operates from a supply voltage of 2V to 6V. The outputs can drive up to 15 LSTTL loads, making it compatible with a wide range of other logic devices. The latch is transparent when the enable (LE) input is high; a D-type input's state then enters the Q outputs. The outputs remain latched at their last state when the LE is low. The output enable (OE) input controls the 3-state outputs. When OE is low, the outputs are enabled; when OE is high, the outputs are in a high-impedance state.
