Nexperia USA Inc. 74LVC86ABQ,115

Overview

74LVC86ABQ,115 from Nexperia is a quad 2-input XOR gate in DHVQFN14 (SOT762-1) 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 delivers propagation delay as low as 2.2 ns (typ.) at 3.3 V and supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in industrial control and embedded I/O expansion circuits.

For engineers reviewing the 74LVC86ABQ,115 datasheet, 74LVC86ABQ,115 pinout, 74LVC86ABQ,115 application, or 74LVC86ABQ,115 equivalent, key selection criteria include input voltage tolerance (5.5 V), thermal-enhanced QFN package suitability for high-density PCBs, guaranteed operation from –40 °C to +125 °C, and compatibility with JEDEC JESD8-7A/5A/C standards for low-voltage logic systems.

Technical Context

This device implements four independent 2-input exclusive-OR logic functions with Schmitt-trigger inputs on all channels, enabling robust signal conditioning for slow-rising or noisy digital signals. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds and supports rail-to-rail input swing across its full 1.2 V–3.6 V VCC range.

It operates under JEDEC-compliant voltage standards including JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and features ESD protection rated at HBM >2000 V and CDM >1000 V - critical for handling in automated assembly and field-deployed equipment.

FAQ

Can 74LVC86ABQ,115 operate reliably at 1.2 V supply?

Yes - the device is fully specified down to 1.2 V VCC per Table 5, with VIH/VIL thresholds scaled accordingly (e.g., VIH = 0.65×VCC min). Static and dynamic parameters including tpd and IOH/IOL are guaranteed across this range, enabling use in ultra-low-power 1.2 V core logic domains.

Is the exposed thermal pad on the DHVQFN14 package required to be soldered?

No - per datasheet section 5.1, the thermal pad (pin 1 index area) has no electrical or mechanical requirement to be soldered. If connected, it must remain floating or tied to GND; improper grounding can disrupt signal integrity or cause latch-up in adjacent circuitry.

Does 74LVC86ABQ,115 support 5 V input signals while powered from 3.3 V?

Yes - inputs tolerate up to 5.5 V regardless of VCC, verified by absolute maximum rating VI = –0.5 V to +6.5 V and functional specification of overvoltage-tolerant inputs. This enables direct connection to 5 V microcontrollers or sensors without external clamping diodes.

How does Schmitt-trigger action improve noise immunity in this XOR gate?

Schmitt-trigger inputs provide hysteresis (typically ~0.3 V at 3.3 V), meaning the rising and falling input thresholds differ. This prevents multiple output transitions when input signals cross the threshold slowly or with superimposed noise - critical for reliable operation with mechanical switches, analog sensor outputs, or long PCB traces.
