SN74LVC823ADWR: 24-Bit Transparent D-Type Latch with 3-State Outputs

The SN74LVC823ADWR from Texas Instruments is a high-performance, 24-bit transparent D-type latch designed for use in systems that require the temporary storage of data. It operates as a memory buffer with 3-state outputs, which allows multiple devices to share a common data bus. This component is part of the LVC family, which is known for its low-voltage operation and compatibility with mixed-voltage system environments.

Key Features:

• Wide Operating Voltage Range: The SN74LVC823ADWR is designed to function with a supply voltage range of 2.7V to 3.6V, making it suitable for low-voltage applications and ensuring compatibility with various logic levels.
• High Drive Capability: The device features high-drive outputs (-24mA IOL) that can drive multiple loads or provide strong signal integrity in long traces or backplane applications.
• Transparent Latch Functionality: The latches are transparent, meaning that when the latch-enable (LE) input is high, the outputs directly reflect the input data. When LE is low, the outputs retain the data that was present just before the transition of LE from high to low.
• 3-State Outputs: The 3-state outputs (OE) allow the latches to be placed in a high-impedance state, effectively disconnecting them from the bus, which is essential for bus-oriented systems.
• Low Power Consumption: Its low-power design is optimized for power-sensitive applications, ensuring minimal power dissipation during operation.
• Edge-Rate Control Circuitry: The SN74LVC823ADWR is equipped with edge-rate control circuitry that significantly reduces noise generation by controlling the output transition times.

Applications:

The SN74LVC823ADWR is ideal for a wide range of applications, including:

• Data storage and buffering in servers and workstations
• Bus interface or bus isolation applications
• Industrial control systems
• Telecommunication infrastructure
• Complex computing systems
