SN74AS1008ADR

Overview

The SN74AS1008ADR 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 a low-level output current of 48 mA and a high-level output current of -48 mA. Propagation delay is specified at 6 ns maximum 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 buffering applications
• Positive-AND logic implementation in circuit designs
• Driver circuits requiring high capacitive-load handling

Procurement Notes

Verify that the ordering suffix 'ADR' corresponds to the SOIC (D) package variant, as indicated by TI documentation. Confirm RoHS compliance status and lead finish specifications via the official Package Option Addendum before procurement. Ensure the component meets the required 0°C to 70°C operating temperature range for your specific application environment.

Selection Notes

Select this component when high-speed AND logic and significant drive current are required. The AS series offers faster propagation delays compared to standard TTL but consumes more power. Verify that the 48 mA output current capability aligns with the load requirements of your target circuitry.

Part Context

This part belongs to the SN74AS1008A family, which includes variants such as SN74AS1008AD and SN74AS1008AN. The 'ADR' designation specifically identifies the surface-mount SOIC package version manufactured by Texas Instruments. It serves as a driver version of the SN74AS08 logic gate.
