SN74ALS251 - 1-of-8 Data Selectors/Multiplexers

Description

These data selectors/multiplexers contain full binary decoding to select one-of-eight data sources and feature controlled complementary 3-state outputs.

The 3-state outputs can interface with and drive data lines of bus-organized systems.

• 3-State Version of the ′ALS151 • 3-State Outputs Interface Directly With System Bus • Perform Parallel-to-Serial Conversion • Complementary Outputs Provide True and Inverted Data • Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs description These data selectors/multiplexers contain full binary decoding to select one-of-eight data sources and feature controlled complementary 3-state outputs. The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (at the high-impedance state), the low impedance of the signal-enabled output drives the bus line to a high or low logic level.
