Product details

Overview

74VHC86M from onsemi is a quad 2-input exclusive-OR gate IC in TSSOP-14 WB package, operating at 2.0–5.5 V supply, with typical propagation delay of 4.8 ns at 5 V and maximum quiescent current of 2.0 µA at 25 °C. It provides pin- and function-compatible replacement for 74HC86 in logic-level translation, parity generation, and digital signal comparison applications.

For engineers reviewing the 74VHC86M datasheet, pinout, applications, or equivalent options, key selection factors include its 5.5 V absolute maximum input voltage tolerance, power-down input protection, low dynamic noise (VOLP ≤ 0.8 V), and guaranteed operation across −40 °C to +85 °C industrial temperature range.

Technical Context

The 74VHC86M implements four independent XOR gates using silicon-gate CMOS technology, enabling high-speed switching while maintaining TTL-compatible propagation delays and CMOS-level power efficiency. Each gate accepts inputs over −0.5 V to 6.5 V regardless of VCC, supporting mixed-voltage interfacing between 3 V and 5 V systems.

Input protection circuitry prevents damage from supply–input voltage mismatch, and all inputs feature power-down protection to avoid unintended current paths during power sequencing. The device complies with JEDEC JESD22-A114-A HBM ESD rating (>2000 V) and uses Pb-free, halogen-free packaging per RoHS.

Key Specifications

Quiescent Supply Current (ICC)	2.0 µA (max.) at TA = 25 °C - enables ultra-low static power in battery-backed or standby circuits
Input Voltage Range (VIN)	−0.5 V to VCC + 0.5 V - allows safe interfacing with overvoltage or floating inputs without external clamping

Pinout & Package

TSSOP-14 WB (Case 948G), 4.9 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, Pb-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	A0–A3, B0–B3 inputs	Eight independent logic inputs - each pair (A/B) feeds one XOR gate; unused inputs must be tied HIGH/LOW
3, 6, 10, 13	O0–O3 outputs	Four open-drain-capable CMOS outputs - rail-to-rail swing, compatible with 3.3 V/5 V logic thresholds
7	GND	Ground reference for all internal circuitry and I/O - requires low-impedance connection to minimize noise coupling
14	VCC	Positive supply terminal - decoupling capacitor (0.1 µF) recommended within 5 mm of pin for stable AC performance

Key Features

Feature	Design Value
High-Speed XOR Logic	tPD = 4.8 ns (typ.) at 5 V - meets timing budgets in synchronous data path and clock-domain crossing circuits
Mixed-Voltage Input Tolerance	Inputs rated −0.5 V to 6.5 V independent of VCC - eliminates level shifters when interfacing 5 V sensors to 3.3 V microcontrollers
Power-Down Input Protection	All inputs protected against back-driving during VCC ramp-up/down - prevents latch-up and current leakage in hot-swap or partial-power-down systems
Low Dynamic Output Noise	VOLP ≤ 0.8 V (max.) at CL = 50 pF - reduces crosstalk and false triggering in dense PCB layouts with shared ground planes
Pb-Free & RoHS Compliance	Halogen-free, BFR-free construction - satisfies IPC-1752A material declaration requirements for automotive and industrial OEMs

Equivalent & Alternatives

The following parts are listed as comparable options for similar XOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HC86D	Higher ICC (max 40 µA at 25 °C), slower tPD (15 ns typ. at 5 V), SO-14 package	Larger footprint, higher static power - suitable only where board space and power budget allow	Select 74HC86D only if TSSOP assembly capability is unavailable and thermal derating permits higher IDDQ
SN74LVC2G86DCUR	Single dual-input XOR in SOT-23-6, 1.65–5.5 V, tPD = 3.7 ns (typ.), lower drive (±24 mA)	Requires four units for quad functionality; no pin compatibility - used in space-constrained, low-pin-count designs	Choose SN74LVC2G86DCUR when minimizing board area outweighs routing complexity and component count increase

Compared with 74VHC86M, 74HC86D trades speed and power efficiency for legacy package availability, while SN74LVC2G86DCUR offers superior speed and voltage flexibility at the cost of discrete integration and layout overhead.

FAQ

What is the absolute maximum input voltage rating for the 74VHC86M?

The 74VHC86M supports DC input voltages from −0.5 V to +6.5 V, independent of VCC level. This allows safe connection to signals exceeding the supply rail-such as 5 V inputs on a 3.3 V-powered system-without external clamping diodes or level shifters, simplifying mixed-voltage interface design.

Does the 74VHC86M require pull-up or pull-down resistors on unused inputs?

Yes-the 74VHC86M datasheet explicitly states that unused inputs must be held HIGH or LOW; they may not float. Floating inputs can cause increased ICC, unpredictable output states, and potential oscillation due to intermediate voltage levels violating VIH/VIL thresholds.

Is the 74VHC86M pin-compatible with the 74HC86 series?

Yes-the 74VHC86M is pin- and function-compatible with the 74HC86 family. Its TSSOP-14 WB footprint matches the physical pinout of 74HC86 variants in SO-14 and TSSOP-14 packages, enabling direct replacement in existing layouts without PCB modification.

What is the maximum capacitive load the 74VHC86M can drive reliably?

The 74VHC86M is characterized up to 50 pF load capacitance in AC electrical specifications, with propagation delay specified at both CL = 15 pF and CL = 50 pF. Driving loads beyond 50 pF may increase tPD nonlinearly and degrade VOLP/VOLV noise margins; external buffering is recommended above this limit.

How does the 74VHC86M handle power sequencing in multi-rail systems?

The 74VHC86M includes power-down protection on all inputs, preventing reverse current flow when VCC is unpowered but input signals remain active. This feature safeguards the device during staggered power-up/down sequences common in battery-backed or hot-swap systems.
