The DM74ALS563N is an octal transparent latch with three-state outputs manufactured by National Semiconductor (now Texas Instruments). This device is designed for temporary storage and buffering of data in digital systems. The 'ALS' designation indicates Advanced Low-power Schottky technology, offering improved speed and power efficiency.

• Low Power Consumption

Benefits

• Provides temporary storage and buffering of eight bits of data.
• Three-state outputs allow for easy connection to bus-oriented systems.
• Advanced Low-power Schottky technology offers improved speed and power efficiency.
• High-speed operation enables use in high-performance systems.
• Low power consumption reduces overall system power requirements.

The DM74ALS563N features eight transparent latches. When the latch enable (LE) input is high, the Q outputs follow the data at the D inputs. When the LE input is low, the data present at the D inputs is latched and stored. The three-state outputs can be enabled or disabled using the output enable (OE) input. When the OE input is high, the outputs are in a high-impedance state. The device operates from a standard 5V power supply. The ALS technology minimizes power consumption while providing high-speed operation. The DM74ALS563N is commonly used in microprocessor systems for buffering address and data lines, and in memory systems for temporary data storage.
