SN54AS250A
- 4-Line to 1-Line Multiplexers That Can Select 1-of-16 Data Inputs
- Applications:
- Boolean Function Generator
- Parallel-to-Serial Converter
- Data Source Selector
- Buffered 3-State Bus Driver Inputs Permit Multiplexing From n Lines to One Line
- Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (NT) and Ceramic (JT) 300-mil DIPs
The ´AS250A devices provide full binary decoding to select 1-of-16 data inputs or use sources as an input with an inverting W\ output. The selected sources are buffered with symmetrical propagation delay times. This reduces the possibility of transients occurring at the output.
A buffered output-enable (
) input can be used for n-line to 1-line cascading.
Taking high places
the output in the high-impedance state. In the high-impedance state,
the output neither loads nor drives the bus lines significantly.
does not affect
the internal operations of the data selector/multiplexer. New data
can be set up while the outputs are disabled.
The SN54AS250A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AS250A is characterized for operation from 0°C to 70°C.
