74LVC2G86DP

Updated: 2026-09-16

Overview

The 74LVC2G86DP is a dual 2-input XOR gate IC from NXP's 74LVC series, optimized for low-voltage digital applications. It operates within a wide voltage range (1.65V to 5.5V), making it suitable for mixed-voltage environments. The IC is built using advanced CMOS technology, ensuring high-speed performance while minimizing power consumption. Its compact design and 5V tolerant inputs allow seamless integration into modern electronic systems, from industrial automation to consumer devices. The 74LVC2G86DP is available in small-form-factor packages like TSSOP and VSSOP, catering to space-constrained PCB designs.

Structure and Working Principle

The 74LVC2G86DP consists of two independent XOR gates, each with two inputs and one output. The XOR (exclusive OR) logic function outputs a high signal only when the inputs differ. This behavior is achieved through a combination of CMOS transistors arranged to perform the XOR operation efficiently. The IC's internal circuitry includes input protection diodes and output drive stages, ensuring robust performance even in noisy environments. Its low-voltage operation is enabled by advanced CMOS process technology, which reduces power dissipation while maintaining high switching speeds.

Key Features

The 74LVC2G86DP stands out for its versatility and efficiency. It supports a broad supply voltage range (1.65V to 5.5V), allowing compatibility with both 3.3V and 5V systems. The IC's 5V tolerant inputs enable interfacing with higher-voltage logic without additional level-shifting components. With propagation delays as low as 3.7 ns at 3.3V, it meets the demands of high-speed applications. The device also features balanced propagation delays and transition times, minimizing signal skew in critical timing circuits. Its ultra-low power consumption (typical ICC of 10 µA) makes it ideal for battery-powered devices.

Application Areas

This IC finds widespread use in digital systems requiring XOR logic functions. Common applications include error detection circuits, parity generators, and arithmetic logic units (ALUs) in microprocessors. It's also employed in data encryption systems and communication interfaces where signal comparison is essential. In embedded systems, the 74LVC2G86DP serves as a building block for state machines and control logic. Industrial applications include PLCs (Programmable Logic Controllers) and sensor interfaces, while consumer electronics utilize it in devices like smart home controllers and portable gadgets.

Maintenance and Precautions

Proper handling of the 74LVC2G86DP is crucial for optimal performance. Always observe ESD (electrostatic discharge) precautions during installation, using grounded workstations and anti-static packaging. The device should be stored in moisture-resistant containers when not in use. Circuit design should include proper decoupling capacitors near the power pins to ensure stable operation. Avoid exceeding the absolute maximum ratings for supply voltage (6V) and input voltage (6.5V). For thermal management, follow recommended PCB layout practices including adequate copper area for heat dissipation.

B2B Procurement Guide

When sourcing the 74LVC2G86DP, verify the manufacturer's authenticity to avoid counterfeit components. NXP Semiconductors is the original manufacturer, but authorized distributors like Arrow, Avnet, and Digi-Key also supply genuine parts. Consider ordering samples for testing before large-volume purchases. Evaluate packaging options (tape and reel vs. cut tape) based on your production requirements. Lead times typically range from 2-8 weeks for standard orders. For cost-sensitive projects, compare prices across multiple suppliers, but prioritize reliability over minimal cost savings to ensure long-term system stability.
