SN74AS832BDWR

Overview

The SN74AS832BDWR is a hex 2-input OR gate from the Texas Instruments AS logic series, housed in a 20-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to +70°C. Key electrical characteristics include a propagation delay of 9 ns, a low-level output current of 15 mA, and a high-level output current of -24 mA.

Feature Summary

• Contains six independent 2-input OR logic gates for parallel signal processing
• Utilizes bipolar transistor technology for high-speed switching performance
• Features push-pull outputs capable of driving significant loads

Applications

• Digital logic circuit design requiring multiple OR functions
• Signal routing and selection in bus systems
• Data path configuration in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the AS logic family specifications align with the target system's speed and power constraints. Ensure the SOIC-20 footprint matches the printed circuit board layout guidelines provided by the manufacturer.

Selection Notes

Select this component when high-speed OR logic operations are necessary within standard 5V logic environments. The AS series offers faster propagation delays compared to standard or ALS variants. Consider the thermal dissipation requirements associated with the bipolar technology and the specific current drive capabilities needed for the connected load circuits.

Part Context

This device belongs to the SN74AS (Advanced Schottky) logic family, known for superior speed-performance-to-power dissipation product ratios. The hex configuration provides multiple logic gates in a single package, reducing component count and board space compared to using individual single-gate ICs.

Replacement Considerations

Check for SN74AS832B without the DWR suffix if tube packaging is acceptable instead of reel. Verify compatibility with other AS-series devices from Texas Instruments for pin-compatible upgrades.
