74LS251 DIP-16 8-to-1 Data Selector/Multiplexer IC (3-State Outputs, TTL, 5V)

Description -

The 74LS251 DIP is a TTL logic integrated circuit that functions as an 8-to-1 data selector/multiplexer in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for high-speed data selection, signal routing, and digital bus interfacing.

The device uses three binary select inputs to route one of eight data inputs to the output. It features 3-state outputs controlled by an Output Enable (OE) input, allowing multiple devices to share a common data bus. The 74LS251 also provides both true (Y) and complementary (W) outputs for flexible digital logic design.
