SN74AS808BNG4

Overview

The SN74AS808BNG4 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 temperature range of 0°C to 70°C. The component features a typical delay time of 3.2 ns with a 50 pF load and maintains power dissipation below 13 mW per gate. It provides high capacitive-drive capability, delivering up to 48 mA low-level output current and -48 mA high-level output current.

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 a typical propagation delay of 3.2 ns under standard loading conditions

Applications

• High-speed digital logic circuits requiring fast switching times
• Data acquisition systems utilizing multiple AND gates
• Industrial control applications operating within standard commercial temperatures

Procurement Notes

Verify the specific package configuration matches the required PCB footprint, as the AS series is available in SOIC, PDIP, LCCC, and CDIP formats. Confirm that the RoHS-compliant status aligns with environmental regulations for the target assembly process. Ensure the ordering suffix corresponds to the exact pin count and lead finish specifications documented in the manufacturer's package option addendum.

Selection Notes

Select this component when designing circuits that require high-speed AND logic operations with significant drive strength. The AS series offers faster performance compared to standard TTL or HC families while maintaining compatible voltage levels. Consider the thermal characteristics and power dissipation limits when integrating multiple gates into dense board layouts.

Part Context

This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for superior speed-performance-to-power dissipation ratios. The 'N' suffix indicates a plastic dual-in-line package variant. As a catalog product, it serves as a standard general-purpose logic solution for commercial applications rather than specialized military or automotive variants.

Replacement Considerations

Direct functional equivalents include the SN74AS808BN and SN74AS808BDW. Verify compatibility regarding package dimensions and lead pitch before substitution.
