Nexperia USA Inc. 74LVC86ADB,118

Overview

74LVC86ADB,118 from Nexperia is a quad 2-input XOR gate in SO14 (SOT108-1) package, operating from 1.2 V to 3.6 V supply, with overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V logic domains and delivers propagation delay as low as 2.2 ns at 3.3 V. Used in digital interface arbitration, parity generation, and mixed-voltage bus control.

For engineers reviewing the 74LVC86ADB,118 datasheet, 74LVC86ADB,118 pinout, 74LVC86ADB,118 application, or 74LVC86ADB,118 equivalent, key selection criteria include input voltage tolerance, propagation delay across VCC range, output drive strength at 3.3 V, and SO14 thermal derating behavior above 100 °C.

Technical Context

This device implements four independent CMOS-based XOR gates with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds defined by VIL ≤ 0.8 V and VIH ≥ 2.0 V at VCC = 3.3 V.

It supports JEDEC-compliant voltage interfaces across three ranges: JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V). Output skew is guaranteed ≤ 1.0 ns between any two outputs switching in the same direction.

FAQ

Can 74LVC86ADB,118 operate at 1.2 V while driving a 50 pF load?

Yes. At VCC = 1.2 V, the device is fully specified with tpd ≤ 11.0 ns into a 30 pF load (per datasheet Table 7). With 50 pF, delay increases predictably per CPD = 12.5 pF (VCC = 1.65 V) scaling; actual measured delay remains within functional timing budgets for sub-20 MHz applications.

Is the exposed pad on the DHVQFN variant (74LVC86ABQ) electrically connected?

No. The thermal pad on SOT762-1 (DHVQFN14) is not an electrical pin. Datasheet section 5.1 explicitly states it has no electrical or mechanical requirement to be soldered; if connected, it must remain floating or tied to GND - it is not internally bonded to VCC or GND.

Does 74LVC86ADB,118 support hot insertion?

No. The device lacks explicit hot-swap protection circuitry. While inputs tolerate 5.5 V, the absence of power-on reset, input current limiting, or VCC sequencing control means uncontrolled hot insertion may cause transient latch-up or excessive ICC surge beyond 100 mA absolute maximum rating.

What is the minimum input transition rate supported with Schmitt-trigger inputs?

At VCC = 3.3 V, the recommended input transition rate is ≥ 10 ns/V (Table 5), meaning a 3.3 V swing should occur within ≥33 ns. Schmitt action ensures reliable switching even below this rate, but propagation delay variance increases beyond ±1.5 ns when rise/fall times exceed 100 ns.
