SN74AS1008ADRG4

Overview

The SN74AS1008ADRG4 is a quadruple 2-input positive-AND buffer/driver from the Texas Instruments AS logic family. 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 device provides high capacitive-drive capability with output currents up to 48 mA. Propagation delays are specified at a maximum of 6 ns under standard load conditions.

Feature Summary

• Contains four independent 2-input positive-AND buffers/drivers
• Offers high capacitive-drive capability for demanding loads
• Performs Boolean functions Y = A • B or Y = A + B in positive logic

Applications

• High-speed digital logic circuits requiring AND functionality
• Buffering applications with significant capacitive loads
• Positive logic signal processing systems

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 'D' suffix indicates a SOIC package while other suffixes may denote different form factors. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the component's active production status aligns with long-term availability needs.

Selection Notes

Select this component when high sink or source current capabilities are necessary for driving heavy loads. The AS series offers faster propagation speeds compared to standard TTL or HC families. Consider the 14-pin SOIC package constraints and ensure adequate thermal management for the operating environment.

Part Context

This part belongs to the SN74AS1008A family, which represents the Advanced Schottky (AS) logic series known for high speed. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing. It serves as a driver version of the SN74AS08, optimized for higher drive strength.

Replacement Considerations

Public confirmed substitute part numbers include SN74AS1008AD, SN74AS1008ADE4, and SN74AS1008AN.
