SN74AS808BDW

Overview

The SN74AS808BDW is a catalog 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 free-air temperature range from 0 °C to 70 °C. The component provides high capacitive-drive capability with a typical delay time of 3.2 ns at a load capacitance of 50 pF. Power dissipation is typically less than 13 mW per gate. It is housed in a 20-pin Plastic Small-Outline (DW) package.

Feature Summary

• Contains six independent 2-input AND drivers for Boolean logic operations
• Provides high capacitive-drive capability for robust signal transmission
• Features low power dissipation characteristics suitable for dense integration

Applications

• High-speed digital logic circuits requiring fast switching times
• Memory systems utilizing AND gating functions
• General-purpose logic applications in industrial environments

Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact physical package, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required operating temperature range and RoHS compliance status for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to validate current production status and availability.

Selection Notes

Select this component when designing circuits that require multiple independent AND gates with high-speed performance and strong drive capabilities. Consider the AS logic family for its balance of speed and power consumption compared to standard TTL or ALS families. Verify that the system's voltage requirements align with the 4.5 V to 5.5 V operating range and that thermal management accommodates the specified power dissipation limits.

Part Context

This device belongs to the Texas Instruments SN54/74AS series, which represents Advanced Schottky TTL technology. The 'SN74' prefix indicates commercial grade operation, while the 'AS' designation signifies the Advanced Schottky logic family known for improved speed over previous generations. The 'DW' suffix specifically identifies the 20-pin Plastic Small-Outline package format.

Replacement Considerations

Direct replacements include other variants within the SN74AS808B family such as SN74AS808BN (PDIP package). For different package types, consider SNJ54AS808BFK (LCCC) or SNJ54AS808BJ (CDIP), noting that military-grade versions may have extended temperature ranges.
