SN74AS1008AD

Overview

The SN74AS1008AD is a quadruple 2-input positive-AND buffer/driver from the Texas Instruments AS logic series. 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 features high capacitive-drive capability with low-level output current of 48 mA and high-level output current of -48 mA. Propagation delay times are specified at a maximum of 6 ns under standard test conditions.

Feature Summary

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

Applications

• High-speed digital logic circuits requiring AND operations
• Buffering and driving applications with high capacitive loads
• Positive logic system implementations

Procurement Notes

Verify that the specific part number matches the required package type, as the SN74AS1008A family includes both SOIC (D) and PDIP (N) options. Confirm RoHS compliance status and lead finish details against the latest Package Option Addendum. Ensure the selected variant aligns with the intended manufacturing process and environmental requirements.

Selection Notes

Select this component when high-speed AND logic functionality is required alongside significant drive strength. The AS series provides faster switching speeds compared to standard TTL but consumes more power. Consider the available package styles based on board space constraints and assembly methods.

Part Context

This device belongs to the SN74AS1008A family, which represents the driver version of the AS08 logic gate. It is designed for applications demanding fast propagation delays and strong output currents. The family is characterized for operation across a standard commercial temperature range.
