74LS244 DIP-20 Octal Non-Inverting Buffer/Line Driver IC (3-State Outputs, TTL, 5V)

Description -

The 74LS244 DIP is a TTL logic integrated circuit that functions as an octal non-inverting buffer and line driver in a 20-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for bus interfacing, memory address buffering, clock distribution, and signal driving in high-speed digital systems.

The device contains eight non-inverting buffers arranged as two independent groups of four, each controlled by its own active LOW output enable input. When enabled, data is transferred directly from the inputs to the outputs. When disabled, the outputs enter a high-impedance (3-state) condition, allowing multiple devices to share a common data bus.
