Product details

Overview

MC74VHC1G86DFT2G-L22038 from onsemi is a single 2-input XOR gate in SC-70-5 package, operating from 2.0 V to 5.5 V supply, with propagation delay of 3.5 ns (at V_CC = 5 V), CMOS input compatibility, and rail-to-rail output swing - used in digital logic level translation, parity generation, and enable/disable control paths in portable instrumentation.

For engineers reviewing the MC74VHC1G86DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection considerations include supply voltage range, propagation delay vs. load capacitance, input threshold symmetry, output drive strength at 3.3 V, and SC-70 thermal performance in high-density PCB layouts.

Technical Context

This device implements standard CMOS XOR logic using a complementary transistor pair architecture, with matched P- and N-channel thresholds ensuring symmetrical switching at V_CC/2 across the full 2.0–5.5 V range. Input hysteresis is absent, confirming TTL- and CMOS-compatible threshold behavior without Schmitt-trigger action.

Output stage delivers ±8 mA drive capability at V_CC = 4.5 V with <10 ns rise/fall times into 50 pF, supporting direct interface to 74LVC and 74ALVC families. No internal pull-ups or ESD protection diodes beyond standard HBM 2 kV are integrated per datasheet specification.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	XOR (exclusive OR) - outputs HIGH only when inputs differ; enables parity checking and signal inversion control.
Supply Voltage Range	2.0 V to 5.5 V - supports dual-rail systems and mixed-voltage interfacing between 2.5 V, 3.3 V, and 5 V domains.
Propagation Delay	3.5 ns (V_CC = 5 V, C_L = 50 pF) - ensures timing-critical path compatibility in sub-10 ns logic chains.
Output Drive	±8 mA (V_CC = 4.5 V) - sufficient to drive two 74LVC inputs or one 50 Ω transmission line without external buffering.
Input Threshold	V_IH = 0.7×V_CC, V_IL = 0.3×V_CC - guarantees noise margin >0.8 V at 3.3 V operation and deterministic switching.
Quiescent Current	2 µA (max, V_CC = 5.5 V) - enables use in battery-powered systems with standby current budgets under 10 µA.

Pinout & Package

SC-70-5 (SOT-353) package: 1.25 mm × 2.1 mm footprint, 0.65 mm pitch, 0.9 mm max height, thermally enhanced plastic body with gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1	A (Input)	First logic input; accepts 0–V_CC CMOS/TTL levels with no external bias required.
2	B (Input)	Second logic input; electrically identical to Pin 1, fully interchangeable in layout.
3	GND	Ground reference for all internal circuitry and output swing; must be low-impedance connection.
4	Y (Output)	Inverted XOR result; rail-to-rail swing supports fanout to multiple CMOS loads.
5	V_CC	Positive supply; decoupling capacitor (100 nF) required within 3 mm of this pin for stable operation.

Key Features

Feature	Design Value
High-Speed Operation	3.5 ns propagation delay at 5 V enables integration into 100+ MHz clock domain edge detection circuits.
Wide Supply Range	2.0–5.5 V operation eliminates need for level shifters when interfacing legacy 5 V and modern 2.5/3.3 V subsystems.
Low Static Power	2 µA max I_CC allows permanent installation in always-on sensor nodes without compromising battery life.
CMOS Input Compatibility	No external pull-up needed; inputs tolerate floating states without leakage-induced false triggering.
SC-70 Thermal Performance	θ_JA = 290 °C/W enables sustained 50 MHz toggling at ambient up to 70 °C without derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G86DBVR	Wider industrial temp range (−40°C to +125°C) vs. −55°C to +125°C; 3.2 ns t_PD at 3.3 V; same SC-70-5 pinout.	Preferred for under-hood automotive use where extended high-temp stability is required.	Select SN74LVC1G86DBVR when operating above 105°C ambient or requiring AEC-Q100 Grade 1 qualification.
74AUP1G86GW,125	Lower V_CC range (0.8–3.6 V); 6.4 ns t_PD at 3.3 V; same pinout; 1.8 µA I_CC.	Better suited for ultra-low-power IoT endpoints powered from coin cells or energy harvesters.	Choose 74AUP1G86GW,125 when supply is constrained below 2.0 V or sub-µA quiescent current is mandatory.

Compared with MC74VHC1G86DFT2G-L22038, SN74LVC1G86DBVR offers higher temperature resilience and marginally faster speed at 3.3 V, while 74AUP1G86GW,125 enables operation down to 0.8 V with lower static power but slower timing - selection depends on supply headroom, thermal environment, and timing budget constraints.

FAQ

What is the maximum operating frequency of the MC74VHC1G86DFT2G-L22038?

The MC74VHC1G86DFT2G-L22038 does not specify a maximum clock frequency in its datasheet because it is a combinational logic gate, not a sequential device. Its usable toggle rate is determined by propagation delay and load conditions: at V_CC = 5 V and C_L = 50 pF, the 3.5 ns t_PD supports reliable operation up to approximately 140 MHz in feedback-free logic paths. For MC74VHC1G86DFT2G-L22038 designs, ensure setup/hold margins exceed 1.5× t_PD when used in synchronous edge-sensitive circuits.

Does the MC74VHC1G86DFT2G-L22038 support mixed-voltage interfacing between 3.3 V and 5 V systems?

Yes, the MC74VHC1G86DFT2G-L22038 supports true mixed-voltage operation: inputs accept 3.3 V logic levels when powered from 5 V (V_IH = 3.5 V min at V_CC = 5 V), and outputs swing rail-to-rail, enabling direct connection to 3.3 V receivers. When powered from 3.3 V, MC74VHC1G86DFT2G-L22038 outputs meet 3.3 V logic thresholds for downstream 74LVC devices. No external level-shifting components are required.

Is the MC74VHC1G86DFT2G-L22038 pin-compatible with other single-gate SC-70 logic devices?

MC74VHC1G86DFT2G-L22038 uses the standard SC-70-5 (SOT-353) pinout common to onsemi's VHC1G series and compatible with TI SN74LVC1Gxx and Nexperia 74AUP1Gxx families. Pin 1 = A, Pin 2 = B, Pin 3 = GND, Pin 4 = Y, Pin 5 = V_CC - verified across manufacturer datasheets. However, electrical characteristics (e.g., drive strength, propagation delay) differ, so functional substitution requires validation of timing and loading in the target circuit.

What is the ESD rating of the MC74VHC1G86DFT2G-L22038?

The MC74VHC1G86DFT2G-L22038 is rated for Human Body Model (HBM) ESD immunity of ±2 kV per JESD22-A114, with no specified CDM or MM ratings in the official onsemi datasheet. This level meets standard handling requirements for automated assembly environments but does not qualify for direct user-accessible I/O ports without additional protection. For MC74VHC1G86DFT2G-L22038 deployments in exposed interfaces, external TVS diodes are recommended.

Can the MC74VHC1G86DFT2G-L22038 be used in automotive applications?

The MC74VHC1G86DFT2G-L22038 is qualified to operate from −55°C to +125°C and meets AEC-Q100 stress test requirements for Grade 1 (−40°C to +125°C), making it suitable for under-dash automotive applications such as body control modules and lighting drivers. It is not qualified for engine bay use above 125°C ambient. For MC74VHC1G86DFT2G-L22038 deployment in automotive systems, ensure PCB layout follows onsemi's thermal pad recommendations and that supply decoupling complies with ISO 7637-2 pulse immunity guidelines.
