Product Overview: SN74ALS563BDWR from Texas Instruments

The SN74ALS563BDWR is a high-quality integrated circuit manufactured by Texas Instruments, a leader in the semiconductor industry. This device falls within the category of latches, specifically an 8-Bit Transparent D-Type Latches with 3-State Outputs. It is designed to meet the needs of complex digital systems, providing a temporary storage solution for data bits that are transferred between different parts of a system.

Key Features

• Logic Type: D-Type Transparent Latch
• Number of Bits per Element: 8
• Output Type: 3-State
• Operating Temperature Range: -40°C to 85°C
• Mounting Type: Surface Mount
• Package / Case: SOIC-20 Wide
• Propagation Delay Time: Fast propagation delay time ensures quick response to input changes.
• Supply Voltage Range: 4.5V to 5.5V, typical 5V logic level operation.

The SN74ALS563BDWR latch is designed for general-purpose storage applications in digital systems. It features a wide operating voltage range, which makes it versatile for various applications. The transparent nature of the latch means that while the enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the data that was present at the inputs at the time the transition occurred is latched and held at the outputs.

Furthermore, the 3-state outputs allow for connection to a bus-oriented system. The outputs can be placed in a high-impedance state, effectively disconnecting the latch from the bus, which is particularly useful in multiplexed data transmission systems or when multiple devices share the same output lines.

The SN74ALS563BDWR comes in a slim SOIC-20 Wide package, which is suitable for surface-mounted technology (SMT). This packaging makes it ideal for modern, compact printed circuit boards where space is at a premium.

Whether used in data buffering, bus interfacing, or register applications, the SN74ALS563BDWR from Texas Instruments provides a reliable and efficient solution for temporary data storage in digital systems. Its fast response time, wide operating voltage range, and robust 3-state outputs make it a versatile choice for designers and engineers looking to enhance the performance and reliability of their electronic projects.
