A20213A - (Pkg 10) SN74ALS251N 1-of-8 Data Selector/Multiplexer (TI)

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. Both outputs are controlled by the output-enable (OE) input. The outputs are disabled when (OE) is high. The SN74ALS251N is characterized for operation from 0°C to 70°C.

Features:
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
