SN74AS153DR

Overview

The SN74AS153DR is a dual 1-of-4 data selector/multiplexer in a 16-pin Small Outline (D) package. It operates from 0°C to 70°C with a supply voltage of 4.5V to 5.5V. Key electrical characteristics include a high-level output current of -15mA and a low-level output current of 48mA. Propagation delays range from 2ns to 12.5ns depending on the input path.

Feature Summary

• Contains two independent 4-line sections with common select inputs A and B
• Includes inverters and drivers for full binary decoding data selection
• Features separate strobe (enable) inputs for each multiplexer section

Applications

• Multiplexing from n lines to one line
• Parallel-to-serial conversion
• Cascading configurations using strobe lines

Procurement Notes

Verify the device status as active production. Confirm RoHS compliance and lead finish specifications (NIPDAU). Ensure the operating temperature range matches the application requirements of 0°C to 70°C. Check moisture sensitivity level ratings before soldering.

Selection Notes

Select this component for applications requiring fast AS-series performance with standard TTL-compatible inputs. The SOIC package is suitable for surface mount designs. Compare against SN74ALS153 for lower power consumption or SN74AS253A if three-state outputs are required.

Part Context

This part belongs to the Texas Instruments SN74AS series, which offers advanced Schottky logic performance. It is functionally compatible with other 74AS multiplexers but provides specific drive capabilities suited for high-speed digital signal routing within commercial temperature ranges.

Replacement Considerations

SN74ALS153DR is a lower-power alternative within the same package. SN74AS253A serves as a three-state version. Verify pinout compatibility and electrical parameter differences when substituting.
