SN74AS250ADWG4

Overview

The SN74AS250ADWG4 is a single 1-of-16 data generator and multiplexer housed in a 24-pin Plastic Small-Outline (DW) package. It operates on a single supply voltage ranging from 4.5V to 5.5V, with an operating temperature range of 0°C to 70°C. The device features buffered 3-state bus driver inputs and provides symmetrical propagation delays for selected data sources. It includes a buffered output-enable input that places the output in a high-impedance state when asserted high.

Feature Summary

• Provides full binary decoding to select one of sixteen data inputs or function as an inverting data source.
• Buffered 3-state bus driver inputs allow efficient multiplexing from multiple lines to a single line.
• Symmetrical propagation delay times reduce the possibility of transients occurring at the output.

Applications

• Boolean Function Generator
• Parallel-to-Serial Converter
• Data Source Selector

Procurement Notes

Verify component authenticity through authorized Texas Instruments channels or certified distributors. Confirm RoHS compliance status and check for obsolete part notifications prior to procurement. Ensure the specific DW package variant matches design requirements. Review datasheet specifications for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this component for applications requiring high-speed 1-of-16 data selection within standard industrial temperature limits. Consider the SN74AS250ANT for through-hole mounting needs. Evaluate the SN54AS250A series if military-grade temperature ranges are required. Verify power supply stability within the 4.5V to 5.5V window to maintain signal integrity.

Part Context

This device belongs to the Texas Instruments 74AS logic family, known for advanced Schottky technology. It serves as a specialized data selector within the broader multiplexer and decoder category. The DW package designation indicates a surface-mount small-outline configuration suitable for automated assembly processes.
