SN74AS02NSR

Overview

The SN74AS02NSR is a quadruple 2-input positive-NOR gate 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 a propagation delay of 6 ns, a low-level output current capability of 32 mA, and a high-level output current of -15 mA. Packaged in a 14-SOIC surface-mount format, it consumes 90 mA of working power supply current.

Feature Summary

• Provides four independent 2-input NOR logic functions
• Delivers high-speed signal processing with 6 ns propagation delay
• Supports heavy capacitive loads via 32 mA low-level sink current

Applications

• High-speed digital logic circuits requiring NOR functionality
• Industrial control systems operating at standard TTL voltages
• Data acquisition systems utilizing surface-mount assembly

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS requirements for your target market. Confirm that the operating temperature range aligns with your system's environmental constraints before finalizing procurement.

Selection Notes

Select this component when high-speed performance is critical compared to standard LS or ALS families. The AS series offers superior speed and drive strength suitable for demanding applications. Verify compatibility with existing 5V logic levels and ensure adequate thermal management for the specified power consumption.

Part Context

This part belongs to the SN74AS00 family of advanced Schottky logic devices. These components are designed for high-speed applications requiring robust noise immunity and fast switching speeds. The SN74AS02 variant specifically implements NOR logic gates within this high-performance series.

Replacement Considerations

Check for SN74AS02N as a potential leaded alternative if surface-mount is not required. Verify pinout compatibility with other AS-series NOR gates.
