74HC244D General Description
The "74HC244D" is a specific digital integrated circuit (IC) commonly used in digital electronics. It belongs to the 74HC family of ICs, which are known for their compatibility with the TTL (Transistor-Transistor Logic) family of digital ICs while offering improved performance and lower power consumption.
Features
Function: The 74HC244D is an octal (8-channel) buffer/line driver with 3-state outputs. It can be used to buffer or amplify digital signals and control whether those signals are actively driving outputs or in a high-impedance state (3-state), which effectively disconnects them from the output.
Supply Voltage: It typically operates with a supply voltage ranging from 2V to 6V, making it suitable for both 3.3V and 5V digital systems.
High-Speed Operation: The "HC" in the part number stands for high-speed CMOS, indicating that this IC is designed for relatively high-speed digital logic applications.
Inputs and Outputs: The 74HC244D has eight inputs and eight 3-state outputs, making it suitable for buffering multiple digital signals.
3-State Outputs: One of the key features of this IC is its 3-state outputs. When the enable input is low, the outputs are in a high-impedance state (disconnected), allowing multiple devices to share a common bus without contention.
Typical Usage: The 74HC244D is often used in digital systems where signal buffering or level shifting is required. It's commonly used in microcontroller-based systems, memory interfaces, and as a general-purpose buffer.
Package Type: The "D" in the part number indicates that it is available in a standard dual in-line package (DIP), which is a through-hole package. It is also available in surface-mount packages like SOIC (Small Outline Integrated Circuit).
Operating Temperature: The IC is designed to operate within a specified temperature range, typically from -40°C to 85°C or similar, depending on the manufacturer's specifications.
Compatibility: The 74HC244D is compatible with other 74HC series ICs and is designed to work with both CMOS and TTL logic families.
