Product Overview: 74AHC573D by NXP Semiconductors
The 74AHC573D is a high-speed Si-gate CMOS device from NXP Semiconductors designed to deliver the functionality of the industry-standard 74 series logic while offering the benefits of low power consumption and high noise immunity. This particular device is an octal D-type transparent latch with 3-state outputs, making it an ideal choice for temporary storage of data and for transferring data from one bus to another, where the bus is a multiplexed representation of multiple data lines.
Key Features
- Logic Family: The device belongs to the AHC (Advanced High-speed CMOS) family, which ensures high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
- Latch Type: The 74AHC573D features eight D-type transparent latches with 3-state outputs. The transparent nature of the latches implies that while the enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the data that met the setup times is latched at the outputs.
- Output Capability: This device can drive 15 LSTTL loads, which is significant for interfacing with traditional TTL logic levels.
- Power Requirements: It operates on a power supply range of 2.0V to 5.5V, accommodating a variety of logic-level requirements and ensuring compatibility with lower voltage systems.
- Package: The 74AHC573D comes in a SO20 package, which is a small-outline package with 20 leads, suitable for surface mount technology (SMT).
Applications
The 74AHC573D is versatile in its application, being suitable for:
- Buffering and storage applications
- Bus interface and bus driver applications
- Control systems where temporary data storage is required
- Communication systems
- Complex data routing and multiplexing
