SN74ALS86DR

Overview

The SN74ALS86DR is a Texas Instruments logic gate featuring four independent 2-input exclusive-OR gates in a 14-pin SOIC package. 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 a low-level output current of up to 8 mA and a high-level output current of -0.4 mA. Propagation delays are specified between 2 ns and 17 ns depending on the input-to-output path and load conditions.

Feature Summary

• Contains four independent 2-input exclusive-OR gates for Boolean logic operations
• Functions as a true/complement element by reproducing or inverting signals based on control inputs
• Supports standard even-parity and odd-parity checking configurations

Applications

• True/complement signal generation
• Even-parity checking circuits
• Odd-parity checking circuits

Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC (D) package with tape-and-reel packaging containing 2500 units. Confirm RoHS compliance status and lead finish details via the official Package Option Addendum, as manufacturing parameters may vary across production revisions.

Selection Notes

Select this component when requiring ALS-speed performance with a 5 V supply. Ensure the application environment remains within the 0°C to 70°C commercial temperature range. Verify that the required drive current does not exceed the 8 mA low-level output specification.

Part Context

This part belongs to the SN74ALS series of advanced low-power Schottky logic devices manufactured by Texas Instruments. It is functionally compatible with other SN74ALS86 variants but is distinguished by its surface-mount SOIC package configuration and commercial temperature rating.

Replacement Considerations

SN74ALS86D is the tube-packaged equivalent. SN74AS86A offers faster switching speeds but requires higher drive currents.
