Product details

Overview

MC74VHC1G86DFT1G from onsemi is a single 2-input XOR gate in ultra-small SC-70-5 (SOT-353) package, operating from 2.0 V to 5.5 V, with propagation delay of 3.5 ns (at V_CC = 5 V), CMOS-level input thresholds, and rail-to-rail output swing - used for logic-level signal comparison and parity generation in space-constrained portable instrumentation.

For engineers reviewing the MC74VHC1G86DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility, propagation delay budget, input hysteresis absence, SC-70 footprint constraints, and TTL/CMOS mixed-signal interface requirements.

Technical Context

The MC74VHC1G86DFT1G implements a true 2-input exclusive-OR logic function using advanced silicon-gate CMOS technology, delivering symmetrical rise/fall times (<4.0 ns at V_CC = 5 V) and guaranteed noise immunity over full industrial temperature range (−40 °C to +85 °C). It features no internal pull-ups or pull-downs, requiring external termination for floating inputs.

Its input structure accepts both TTL- and CMOS-compatible logic levels across the entire 2.0–5.5 V supply range, and its output drives ±8 mA at V_CC = 4.5 V, supporting direct interfacing with 74LVC, 74ALVC, and other 3.3 V logic families without level-shifting circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	XOR (exclusive OR) - outputs HIGH only when inputs differ; essential for error detection and arithmetic carry logic.
Supply Voltage Range	2.0 V to 5.5 V - enables interoperability across 2.5 V, 3.3 V, and 5 V system domains without voltage translation.
Propagation Delay	3.5 ns (max) at V_CC = 5 V - supports >100 MHz toggle rates in critical timing paths of serial data framing circuits.
Output Drive	±8 mA at V_CC = 4.5 V - sufficient to drive two 74LVC inputs or one 50 Ω transmission line under controlled impedance conditions.
Input Threshold	V_IH = 0.7×V_CC, V_IL = 0.3×V_CC - ensures robust switching margin against supply ripple and crosstalk in dense PCB layouts.
Operating Temperature	−40 °C to +85 °C - qualified for industrial-grade embedded control and sensor interface applications.

Pinout & Package

SC-70-5 (SOT-353) surface-mount package: 1.25 mm × 2.1 mm footprint, 0.95 mm height, 0.65 mm lead pitch, thermally enhanced plastic body with gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1	A (Input)	First logic input; must be actively driven or terminated to avoid undefined state due to lack of internal biasing.
2	GND	Ground reference for all internal circuitry and output stage; requires low-inductance connection to system ground plane.
3	B (Input)	Second logic input; electrically identical to Pin 1; differential routing recommended for high-noise environments.
4	Y (Output)	Inverted XOR result; rail-to-rail swing supports direct connection to downstream CMOS inputs without series resistance.
5	V_CC	Positive supply; decoupling capacitor (0.1 µF ceramic) required within 3 mm of this pin for stable high-speed operation.

Key Features

Feature	Design Value
Ultra-small SC-70-5 package	Reduces board area by >60% vs. SOIC-5; enables placement adjacent to BGA processors or RF modules.
Wide 2.0–5.5 V supply range	Eliminates need for dedicated level shifters in mixed-voltage systems such as USB-C PD controllers with 3.3 V MCU and 5 V peripheral rails.
3.5 ns max propagation delay	Supports real-time XOR-based CRC-8 computation in UART frame validation without pipeline stalls.
No input hysteresis	Enables precise edge-aligned logic sampling in synchronous clock domains where Schmitt-trigger behavior would distort timing margins.
±8 mA output drive	Drives standard 50 Ω coaxial test probe directly during in-circuit logic verification without external buffer.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G86DBVR	Same SC-70-5 package; 1.65–5.5 V supply; 3.7 ns max t_PD; higher I_OFF leakage at V_CC = 0 V.	Slightly wider voltage range but lower noise margin below 2.0 V; suitable for battery-backed systems with brown-out detection.	Select when interfacing with 1.8 V logic or requiring guaranteed operation down to 1.65 V.
74AUP1G86GW,125	SC-70-5; 0.8–3.6 V supply; 6.4 ns max t_PD; 0.9 µA typical I_CC at 3.3 V - ultra-low static power.	Optimized for sub-1 V core domains; not compatible with 5 V systems; slower but more energy-efficient in always-on sensor nodes.	Select when minimizing quiescent current is prioritized over speed in coin-cell-powered devices.

Compared with SN74LVC1G86DBVR and 74AUP1G86GW,125, the MC74VHC1G86DFT1G delivers the fastest propagation delay in the 2.0–5.5 V range and maintains superior noise immunity above 3.3 V, making it optimal for mixed-voltage industrial interfaces where timing precision and voltage headroom are critical.

FAQ

What is the maximum operating frequency supported by the MC74VHC1G86DFT1G?

The MC74VHC1G86DFT1G does not specify a maximum clock frequency in its datasheet because it is a combinational logic device without an internal clock. Its usable toggle rate is determined by propagation delay: with a typical t_PD of 3.5 ns, the MC74VHC1G86DFT1G supports reliable operation up to approximately 140 MHz in feedback-free configurations, assuming matched trace lengths and proper termination.

Can the MC74VHC1G86DFT1G operate with a 1.8 V supply?

No, the MC74VHC1G86DFT1G is not rated for 1.8 V operation. Its absolute minimum supply voltage is 2.0 V per the datasheet. Attempting to power the MC74VHC1G86DFT1G at 1.8 V may result in undefined logic states, increased propagation delay, or failure to switch - use SN74LVC1G86DBVR or 74AUP1G86GW,125 instead for 1.8 V compatibility.

Does the MC74VHC1G86DFT1G have built-in ESD protection?

Yes, the MC74VHC1G86DFT1G includes on-chip ESD protection diodes rated to ±2 kV HBM (Human Body Model) per JESD22-A114. This provides baseline handling robustness during assembly but does not replace system-level TVS protection for I/O lines exposed to external connectors - especially critical when using the MC74VHC1G86DFT1G in USB or industrial fieldbus interfaces.

Is the MC74VHC1G86DFT1G pin-compatible with older 74HC logic variants?

No, the MC74VHC1G86DFT1G uses the SC-70-5 (SOT-353) package, which is not pin-compatible with through-hole or SOIC packages used by legacy 74HC86 variants. While the logic function matches, physical layout adaptation is required. The MC74VHC1G86DFT1G replaces discrete 74HC86 functions in miniaturized designs, not as a drop-in upgrade for existing SOIC footprints.

How should unused inputs be handled on the MC74VHC1G86DFT1G?

Unused inputs on the MC74VHC1G86DFT1G must be tied to a defined logic level - either V_CC or GND - using a pull-up or pull-down resistor (10–100 kΩ typical). Leaving inputs floating causes unpredictable output states, increased supply current, and potential oscillation due to the absence of internal biasing or hysteresis in the MC74VHC1G86DFT1G input structure.
