SN74AS353BDR

Overview

The SN74AS353BDR is a dual 1-of-4 data selector/multiplexer from Texas Instruments' AS logic series. It features two independent multiplexers with three-state outputs, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to +70°C. Key electrical characteristics include a propagation delay of 5 ns and high-speed performance typical of the AS series, designed for TTL-compatible inputs.

Feature Summary

• Dual independent 1-of-4 multiplexer architecture
• Three-state output capability for bus driving
• High-speed AS series logic performance
• TTL-compatible input levels

Applications

• Data routing in digital systems
• Signal selection in measurement equipment
• Bus interface circuits

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm package type is 16-SOIC. Check lead-free status carefully due to conflicting supplier data. Ensure operating temperature range matches application requirements of 0 to 70 degrees Celsius.

Selection Notes

Select this component when dual channel signal switching with high speed is required. The AS series offers faster propagation than standard LS or ALS families. Three-state outputs allow direct connection to system buses without external tri-state buffers.

Part Context

Part of the Texas Instruments SN74AS353 series, which provides dual multiplexing functions. The 'BDR' suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes in high-volume manufacturing environments.

Replacement Considerations

Check for SN74AS353N (PDIP) if through-hole mounting is needed. Verify pin compatibility with other AS-series multiplexers. No direct single-source substitute identified in provided data.
