SN74AS808BDWRE4

Overview

The SN74AS808BDWRE4 is a high-speed logic device containing six independent 2-input AND drivers. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to 70°C. The component features a typical propagation delay time of 3.2 ns with a load capacitance of 50 pF, alongside a typical power dissipation of less than 13 mW per gate. It utilizes a 20-pin Small-Outline (DW) package.

Feature Summary

• Contains six independent 2-input AND drivers performing Boolean functions in positive logic
• Provides high capacitive-drive capability for robust signal transmission
• Features low typical power dissipation per gate for energy efficiency

Applications

• High-speed digital logic circuits requiring multiple AND operations
• Data bus buffering and driving applications
• Industrial control systems operating within standard commercial temperature ranges

Procurement Notes

Verify the specific ordering suffix 'E4' against current Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Ensure the procurement channel provides valid traceability for the SOIC-20 package variant. Confirm that the delivered components match the active production status indicated in the latest package option addendum.

Selection Notes

Select this component when designing circuits requiring six independent AND gates with high-speed performance characteristics. Consider the AS logic series for its superior speed compared to standard TTL alternatives. Verify that the system power supply remains strictly within the 4.5 V to 5.5 V range to ensure reliable operation and prevent damage to the internal circuitry.

Part Context

This part belongs to the Texas Instruments SN54/74AS series of advanced Schottky logic devices. The SN74AS808B variant is specifically characterized for commercial temperature ranges, distinguishing it from the military-grade SN54AS808B. It serves as a fundamental building block for complex digital logic designs requiring fast switching speeds and high drive currents.

Replacement Considerations

Direct replacements include SN74AS808BDW or SN74AS808BN depending on the required package type. Cross-series equivalents like SN74ALS808 offer similar functionality but with different electrical characteristics.
