The 74LVC573ATTR from STMicroelectronics is a high-performance, octal D-type transparent latch that is designed to meet the requirements of high-speed memory buffering with low-power consumption. This integrated circuit is part of the 74LVC family, which is known for its low-voltage operation and compatibility with TTL levels.

Key Features

• Wide Operating Voltage: The device operates on a voltage range of 1.2V to 3.6V, making it suitable for battery-operated and low-power applications.
• High-Speed Performance: With a typical propagation delay of only a few nanoseconds, this latch is optimized for high-speed data transfer and processing.
• Low Power Consumption: It features a very low static power consumption and minimal increase in dynamic power with frequency, thus conserving energy in your designs.
• Bus Hold Function: The 74LVC573ATTR includes a bus hold feature, which maintains the last valid input state when no input is present, eliminating the need for external pull-up or pull-down resistors.
• High Drive Capability: The device can source or sink up to 24 mA, providing robust drive capability for connected components.
• Compatibility: Input levels are compatible with 5V TTL levels, which allows for easy integration into mixed-voltage systems.
