SN74AHC573N Octal Transparent D-Type Latches

The SN74AHC573N, manufactured by Texas Instruments, is a high-performance, octal transparent D-type latch with a wide operating voltage range and high-speed operation. This integrated circuit is designed to be used in applications that require the temporary storage of data and is particularly suited for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The device features eight D-type latches with 3-state true outputs. The latches are transparent, meaning that while the latch-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 D inputs at the time the transition occurred is retained at the Q outputs until LE is returned high again.

Key Features:

• Logic Type: Octal D-Type Transparent Latch
• Number of Channels: 8
• Output Type: 3-State Outputs
• Operating Voltage Range: 2V to 5.5V
• High On-Off Output Voltage Ratio: Ensures a clear distinction between high and low logic levels.
• Low Crosstalk Between Switches: Minimizes interference and signal distortion.
• Fast Propagation Delay Times: Suitable for high-speed data processing.
• Latch-Up Performance Exceeds 250 mA Per JESD 17: Provides robustness against latch-up events.

Applications:

The SN74AHC573N is versatile and can be used in a variety of electronic systems, including:

• Microprocessor or Microcontroller Interface
• Data Storage and Retrieval
• Communication Systems
• Industrial Control Systems
• Portable Electronics

Its DIP (Dual In-line Package) makes it easy to handle for prototyping or for use in through-hole PCB designs. The SN74AHC573N is characterized for operation from -40°C to 85°C, making it reliable in a wide range of environmental conditions.

With its combination of high-speed operation, wide operating voltage range, and robust latch-up performance, the SN74AHC573N from Texas Instruments is an excellent choice for designers looking to implement secure data storage within their digital logic systems.
