Product details
Overview
MC74VHC86DT from onsemi is a quad 2-input XOR gate IC in TSSOP-14 package, operating from 2.0 V to 5.5 V, with typical propagation delay of 4.8 ns at 5 V and input tolerance up to 7 V for mixed-voltage interfacing. It delivers CMOS-speed performance with TTL-equivalent timing while maintaining low static current (2 µA max at 25°C) and is used in digital logic level translation, parity generation, and arithmetic circuits.
For engineers reviewing the MC74VHC86DT datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.5 V absolute maximum supply rating, 7 V input overvoltage tolerance, balanced tPLH/tPHL propagation delays, Pb-free TSSOP-14 packaging, and compatibility with 3 V/5 V system interfacing.
Technical Context
The MC74VHC86DT implements four independent XOR gates using silicon-gate CMOS technology with three-stage internal buffering to ensure high noise immunity (VNIH/VNIL = 28% VCC) and stable output drive. Its inputs are 7 V tolerant, enabling direct connection between 5 V controllers and 3 V logic subsystems without external level shifters.
It features power-down protection on all inputs, latchup immunity exceeding 300 mA, and ESD robustness per HBM > 2000 V. The device supports operation across –55°C to +125°C and exhibits balanced propagation delays and low dynamic noise (VOLP ≤ 0.8 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APW | Lower VCC min (1.65 V), higher ICC (10 µA), same TSSOP-14 footprint. | Better suited for 1.8 V systems; less suitable for wide-voltage industrial use. | Select when operating below 2.0 V or requiring tighter 1.8 V logic compatibility. |
| 74AHC86PW | Higher speed (tPD = 3.7 ns typ), wider VCC range (2–5.5 V), same pinout. | Superior for high-frequency clock-domain logic; slightly higher dynamic power. | Select when propagation delay < 4.0 ns is required and supply stability supports AHC family noise margins. |

FAQ
What is the absolute maximum input voltage rating for MC74VHC86DT?
The MC74VHC86DT supports DC input voltages from –0.5 V to +7.0 V, independent of VCC. This 7 V tolerance allows safe interfacing with 5 V logic outputs even when the device operates at 3.3 V or lower, eliminating external clamping components. Exceeding this rating risks permanent damage to input structures.
Does MC74VHC86DT support operation at 2.0 V supply?
Yes, MC74VHC86DT is fully specified down to VCC = 2.0 V per its Recommended Operating Conditions. At 2.0 V, propagation delay increases to 11.0 ns (max, CL = 15 pF), and output drive reduces to ±2 mA, but logic functionality remains guaranteed across –55°C to +125°C. This makes MC74VHC86DT suitable for battery-powered 2.0–2.5 V systems.
Is MC74VHC86DT pin-compatible with standard 74-series XOR gates?
Yes, MC74VHC86DT is pin- and function-compatible with industry-standard 74LS86, 74HC86, and 74HCT86 in TSSOP-14 packages. Its pinout matches the 14-lead SOIC and TSSOP footprints defined in JEDEC MS-012, enabling drop-in replacement where voltage and speed requirements align - confirmed by onsemi's "Pin and Function Compatible" feature statement.
What is the thermal resistance (θJA) of the MC74VHC86DT package?
The MC74VHC86DT in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 165°C/W under standard JEDEC JESD51-2 conditions (single-layer 1-in² copper pad). Derating is –6.1 mW/°C above 65°C ambient, limiting max continuous power dissipation to 450 mW at 125°C ambient per the datasheet's Absolute Maximum Ratings table.
Can unused inputs on MC74VHC86DT be left floating?
No - unused inputs on MC74VHC86DT must be tied to a valid logic level (VCC or GND) to prevent metastability, increased ICC, and potential oscillation. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC)." Floating inputs may cause excessive current draw or erratic output behavior due to undefined threshold crossing.
