Diodes Incorporated 74LVC1G86FS3-7

Overview

74LVC1G86FS3-7 from Diodes Incorporated is a single 2-input XOR gate in a 4-pin X2-DFN0808-4 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial power-down protection. It performs the Boolean function Y = A ⊕ B and is used for voltage-level shifting and signal isolation in compact portable electronics.

For engineers reviewing the 74LVC1G86FS3-7 datasheet, 74LVC1G86FS3-7 pinout, 74LVC1G86FS3-7 application, or 74LVC1G86FS3-7 equivalent, key selection criteria include its ultra-small 0.8mm × 0.8mm footprint, guaranteed 5ns propagation delay at 3.3V, IOFF-enabled power-down isolation, and compatibility with mixed-voltage 1.8V/3.3V/5V logic domains.

Technical Context

This device implements a positive-logic exclusive OR function (Y = A·B̅ + Ā·B) using CMOS technology, supporting bidirectional voltage translation between differing logic families due to 5.5V-tolerant inputs and rail-to-rail push-pull outputs. Its IOFF circuit actively disables output leakage during VCC = 0V, preventing back-current in partial-power-down systems.

Designed for low-power embedded signal routing, it features input hysteresis-free switching, operates across –40°C to +125°C, and maintains consistent timing performance (tpd ≤ 6.5ns max at 3.3V, –40°C to +125°C) without external biasing or pull-ups.

FAQ

What is the maximum operating temperature for 74LVC1G86FS3-7?

The device is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature reaching up to +150°C under worst-case power dissipation. Thermal resistance θJA = 400°C/W in the X2-DFN0808-4 package means typical power dissipation below 50mW keeps junction rise under 20°C above ambient.

Does 74LVC1G86FS3-7 require external pull-up or pull-down resistors on inputs?

No. Inputs are CMOS-compatible with high impedance (>10MΩ) and no internal termination; however, per datasheet Note 9, unused inputs must be externally tied to VCC or GND to prevent floating states and excessive ICC. No pull resistors are needed for functional inputs.

Can 74LVC1G86FS3-7 be used in 5V-only systems?

Yes. With VCC = 5.0V, it delivers 32mA output drive, 5.5ns max propagation delay, and full 5.5V input tolerance. Its logic thresholds scale with VCC (VIH ≥ 0.7×VCC), ensuring reliable switching at 5V while maintaining compatibility with lower-voltage sources.

Is the X2-DFN0808-4 package lead-free and RoHS compliant?

Yes. The 74LVC1G86FS3-7 is fully RoHS 2 compliant (2011/65/EU), lead-free, halogen-free, and antimony-free per Diodes Incorporated's "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb), with no purposely added lead and full traceability documentation available.
