SN74AS808BN

Overview

The SN74AS808BN 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 features a typical delay time of 3.2 ns with a capacitive load of 50 pF, while maintaining typical power dissipation below 13 mW per gate. It utilizes a standard plastic 300-mil DIP package with 20 pins.

Feature Summary

• Contains six independent 2-input AND drivers for Boolean logic operations
• Provides high capacitive-drive capability for signal integrity
• Delivers high-speed performance with low propagation delay times

Applications

• High-speed digital logic circuit design
• Data acquisition systems requiring fast processing
• Industrial control applications

Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the standard plastic 300-mil PDIP package when sourcing components. Confirm that the required operating environment remains within the specified 0 °C to 70 °C temperature range. Ensure the system supply voltage strictly adheres to the 4.5 V to 5.5 V limits to maintain reliable operation and prevent damage to the internal circuitry.

Selection Notes

Select this component for designs requiring multiple independent AND gates in a single integrated circuit. Consider its AS logic family characteristics for applications demanding faster switching speeds compared to standard TTL alternatives. Evaluate the 20-pin DIP footprint against available board space and routing constraints during the initial schematic capture phase.

Part Context
