Diodes Incorporated 74LVC1G86W5-7

Overview

74LVC1G86W5-7 from Diodes Incorporated is a single 2-input XOR gate in SOT25 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 portable logic interfaces.

For engineers reviewing the 74LVC1G86W5-7 datasheet, 74LVC1G86W5-7 pinout, 74LVC1G86W5-7 application, or 74LVC1G86W5-7 equivalent, key selection criteria include its 1.65–5.5V VCC range, 5.5V input tolerance, IOFF-enabled power-down safety, and 2.3ns typical propagation delay at 3.3V.

Technical Context

This device implements a positive-logic exclusive OR function (Y = A·B̅ + Ā·B) using CMOS technology, supporting mixed-voltage interfacing due to 5.5V-tolerant inputs independent of VCC level. Its IOFF circuit actively disables outputs during power-down to prevent backflow current.

Designed for low-power embedded logic, it meets JESD22 ESD ratings (>2kV HBM, >2000V HBM, >1000V CDM) and JESD78 latch-up immunity (>100mA), with input thresholds scaling with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V).

FAQ

Can 74LVC1G86W5-7 operate with VCC = 1.5V?

No. The absolute minimum recommended VCC is 1.65V per DS32201 Rev. 9–2. At 1.5V, output drive strength collapses below specification, and input thresholds become undefined. Data retention is supported down to 1.5V, but functional operation requires ≥1.65V.

Is Pin 3 (GND) internally connected to the SOT25 exposed pad?

No. The SOT25 package for 74LVC1G86W5-7 has no thermal pad; Pin 3 is the sole GND connection. Diodes' official package outline confirms no exposed metal pad - all five terminals are perimeter leads.

Does IOFF activate automatically when VCC drops below threshold?

Yes. IOFF engages when VCC falls below approximately 0.2V, disabling both output pull-up and pull-down FETs regardless of input states. This prevents back-current from driven inputs into the powered-down device, as verified in the "Partial Power Down" section of the datasheet.

What is the maximum capacitive load this device can drive reliably?

At 3.3V VCC and 25°C, the device maintains specified VOL and VOH up to 50pF load capacitance, based on standard test conditions (RL = 500Ω, CL = 50pF). For loads >50pF, propagation delay increases linearly (~0.5ns/pF), and rise/fall times degrade - layout decoupling and local buffering are recommended beyond 100pF.
