SN74AS286DR

Overview

The SN74AS286DR is a quadruple exclusive-OR gate manufactured by Texas Instruments, belonging to the AS logic series. It features four independent XOR circuits with two inputs each, housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation. Key electrical parameters include a low-level output current of 20 mA, a high-level output current of -2 mA, and an average propagation delay of 10 ns at 5 V with 50 pF load capacitance. The component is rated for operation between 0°C and +70°C.

Feature Summary

• Provides four independent exclusive-OR logic functions for data comparison or arithmetic operations
• Features ultra-high-speed bipolar technology with propagation delays under 10 ns
• Delivers strong push-pull output drive capability suitable for bus-oriented systems

Applications

• Data comparison circuits requiring fast parity checking
• Arithmetic logic units performing addition or subtraction
• Digital communication systems utilizing error detection mechanisms

Procurement Notes

Verify the specific ordering suffix DR against the manufacturer's official datasheet to confirm the SOIC-14 package type and tape-and-reel packaging configuration. Ensure that the AS series designation aligns with system requirements for bipolar power consumption and speed characteristics compared to alternative logic families.

Selection Notes

Select this component when high-speed XOR functionality is required within standard 5 V logic environments. The AS series offers superior speed over LS or ALS counterparts but consumes more power. Confirm that the 20 mA output drive strength meets the capacitive loading requirements of the connected loads without exceeding thermal limits.

Part Context

This part belongs to the Texas Instruments SN74AS00 series, which represents advanced Schottky bipolar logic technology. The series is designed for applications demanding faster switching speeds than standard TTL while maintaining compatible logic levels. The SN74AS286 specifically implements the exclusive-OR function commonly used in digital signal processing and control applications.
