The 74HCT373MTCX is an octal D-type transparent latch with 3-state outputs manufactured by Fairchild/ON Semiconductor. This device is designed as a high-speed CMOS logic latch, ideal for applications requiring temporary data storage and interfacing with microprocessor systems. The 3-state outputs enable multiple devices to share a common data bus, improving data transfer efficiency.
Applications:
- Microprocessor Systems: Interfacing microprocessors with memory and peripheral devices.
- Data Buffering: Temporarily storing data during data transfer operations.
- Address Latching: Capturing address signals for memory access.
- Memory Interfacing: Providing a convenient interface between memory and other system components.
- Data Bus Isolation: Isolating sections of a data bus to prevent conflicts and improve performance.
Features:
- Octal D-Type Latch: Contains eight independent D-type latches in a single package.
- 3-State Outputs: The outputs can be in a high, low, or high-impedance state.
- High-Speed CMOS: Provides fast switching speeds and low power consumption.
- TTL Compatibility: Input logic levels are compatible with TTL voltage levels.
- Wide Operating Voltage Range: Typically operates from 4.5V to 5.5V.
Benefits:

Additional Details:
The 74HCT373MTCX is characterized by its propagation delay, quiescent current, and operating voltage range. The 3-state outputs are controlled by an Output Enable (OE) input, which, when high, places the outputs in a high-impedance state, effectively disconnecting the latch from the bus. Data is latched when the Latch Enable (LE) input is high and the data at the D inputs is transferred to the outputs. When LE goes low, the data is latched and remains stored. The device is provided in a surface-mount SOIC (Small Outline Integrated Circuit) package which allows for efficient use of board space and automated assembly. Its TTL-compatible inputs and CMOS technology make it a versatile component for a wide range of applications, including computer systems, industrial control, and data acquisition systems.
