Latches Texas Instruments CD74HC573E Overview
The CD74HC573E from Texas Instruments is a high-performance, octal D-type latch integrated circuit designed for a wide array of applications that require the retention of binary information for a specific duration of time. This IC enables seamless data flow from the input bus to the output bus, maintaining data integrity by locking the data when the latch enable (LE) input is held high. Fabricated using advanced silicon-gate CMOS technology, the CD74HC573E ensures low power consumption while providing high speeds, making it an ideal choice for interfacing with bus-oriented systems where data integrity and operational efficiency are critical. As a latch-type component, this device is pivotal in systems where temporary data storage and transfer stability are required, positioning itself as an indispensable tool for developers and engineers in both commercial and industrial sectors.
CD74HC573E Features
The CD74HC573E latch offers several key features that enhance its applicability in sophisticated digital systems:
- 3-state outputs for bus-oriented applications.
- Wide operating voltage range of 2V to 6V.
- Low power consumption with a typical ICC of only 20 µA.
- High noise immunity characteristic of CMOS technology.
- Significant drive capability, with output drive at 7.8 mA at 5V.
- Compatible with all forms of logic circuits.
- Available in a 20-pin DIP package, facilitating easy integration into a variety of board layouts.
CD74HC573E Applications
- Microprocessor Systems: The CD74HC573E is used to latch input data, allowing the processor to perform other tasks without data loss.
- Data Buffering: Acts as a temporary data buffer between asynchronous systems, ensuring data integrity during transfer.
- Data Bus Interface: Provides a stable state output to data buses, preventing errors in multi-source systems.
- Industrial Control Systems: Used in systems requiring robust data handling and error-free output for reliable industrial operations.
- Communication Equipment: Ensures reliable data storage and transfer in communication devices requiring high-speed data handling.
