Latches Texas Instruments CD74HC373M Overview
The Latches Texas Instruments CD74HC373M is a high-performance octal transparent D-type latch designed for applications requiring the storage and retrieval of data under controlled conditions. Its compact 20SOIC package houses eight latches with 3-state outputs, providing a practical solution for a wide range of digital interfacing problems. This integrated circuit is characterized by its ability to remain transparent until output enable (OE) is taken high, at which point the latched data remains isolated yet accessible. This feature makes the CD74HC373M ideal for implementing buffer registers, control registers, and power-on initialization stages in digital systems.
CD74HC373M Features
- Eight D-type latches in a single package for density optimization.
- 3-state outputs for bus interfacing, allowing multiple components to share the same output lines.
- Wide operating voltage range from 2V to 6V accommodating diverse logic levels and interfacing scenarios.
- High current output drive (-7.8mA/IOL, 7.8mA/IOH) suitable for driving LEDs and other output devices.
- Low power consumption and minimal propagation delay, enhancing overall system efficiency and responsiveness.
CD74HC373M Applications
- Microprocessor Systems: Acts as an interface buffer between the microprocessor and other parts of the digital system, ensuring data integrity during high-speed operations.
- Communication Equipment: Used in data storage registers to temporarily hold data during the processing and transfer phases in various communication protocols.
- Portable Devices: Provides low-power, high-efficiency latching capabilities, crucial for battery-operated devices requiring extended operational times.
- Data Acquisition Systems: Employs its fast latching ability to capture and store data accurately in real-time measurement setups.
- Industrial Control: Functions as a control register in automation machinery, holding command signals that control various stages of industrial processes.
