SN74LS244N (74LS244) Logic chip

Description:

The SN74LS244N is an octal buffer/line driver IC designed to be used as a bus interface for various digital systems. It features eight independent buffers with tri-state outputs, each capable of driving outputs directly or serving as input buffers for systems requiring high-speed TTL-compatible logic. This IC is particularly useful in applications where multiple devices need to share data lines while maintaining signal integrity and noise immunity.

Key Features:

• Octal buffer/line driver with tri-state outputs
• TTL-compatible inputs and outputs
