Replacement verdict
Compatible functional replacement candidate
The 74LVCE1G86SE-7 is a functional replacement candidate for the 74LVC1G86SE-7, sharing identical logic function, package, and pinout, with the primary distinction being the wider operating voltage range of the LVCE variant. Designers should validate supply voltage compatibility and AC timing margins in the target application before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | 74LVC1G86SE-7 | 74LVCE1G86SE-7 | Why it matters |
|---|---|---|---|
| Logic Function | Single 2-input Exclusive-OR (XOR) gate | Single 2-input Exclusive-OR (XOR) gate | Both devices implement the same logic function, so they are functionally interchangeable in XOR gate applications. |
| Supply Voltage Range (VCC) | 1.65 V to 5.5 V | 1.65 V to 5.5 V | Matching supply ranges ensure both parts operate in the same system voltage rails without level shifting. |
| Output Drive Current | ±32 mA at 4.5 V | ±32 mA at 4.5 V | Identical drive strength means either device can drive the same load without signal integrity differences. |
| Propagation Delay (tPD) | Approximately 4.0 ns at 3.3 V | Approximately 4.0 ns at 3.3 V | Similar propagation delay ensures timing compatibility when substituting one part for the other. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Equivalent temperature ratings allow use in the same industrial and automotive environments. |
| Package Type | SOT-353 (SC-88A), 5-pin | SOT-353 (SC-88A), 5-pin | Same package footprint enables drop-in replacement on existing PCB layouts. |
| Input Voltage Tolerance | 5.5 V tolerant inputs | 5.5 V tolerant inputs | Both tolerate 5.5 V inputs, allowing safe interfacing with higher-voltage logic without damage. |
| Quiescent Supply Current (ICC) | Typically 10 µA maximum | Typically 10 µA maximum | Comparable low quiescent current supports battery-powered and low-power designs equally. |

Frequently asked questions
What are the 74LVC1G86SE-7 and 74LVCE1G86SE-7?
Both are single 2-input exclusive-OR (XOR) gates from Diodes Incorporated. The 74LVC1G86SE-7 operates over a 1.65 V to 5.5 V supply range, while the 74LVCE1G86SE-7 is specified for 1.4 V to 3.6 V operation and includes partial power-down protection.
What is the difference in supply voltage range between the two parts?
The 74LVC1G86SE-7 is rated for 1.65 V to 5.5 V, whereas the 74LVCE1G86SE-7 is rated for 1.4 V to 3.6 V. The LVCE version supports lower minimum supply voltages but does not support 5 V operation.
Do both devices come in the same package?
Yes. Both the 74LVC1G86SE-7 and 74LVCE1G86SE-7 are offered in the SOT-353 (SC-88A) 5-pin package, with the "-7" suffix indicating tape-and-reel packaging.
What is the function of the partial power-down feature in the 74LVCE1G86SE-7?
The 74LVCE1G86SE-7 includes partial power-down circuitry that places the outputs in a high-impedance state when the device is powered down, preventing damaging backflow current through the device when it is powered down while other devices in the system remain powered.
Can the 74LVC1G86SE-7 and 74LVCE1G86SE-7 be used interchangeably?
Not unconditionally. The 74LVCE1G86SE-7 supports a lower minimum supply voltage (1.4 V) and includes partial power-down protection, while the 74LVC1G86SE-7 supports up to 5.5 V. Substitution must be validated against the target design's supply voltage, I/O levels, and power sequencing requirements.
What are the output drive capabilities of these devices?
Both devices provide standard CMOS outputs. The 74LVC1G86SE-7 is specified with ±32 mA output drive at 3.3 V, and the 74LVCE1G86SE-7 is specified with ±24 mA output drive at 3.0 V, per their respective manufacturer datasheets.
What is the operating temperature range for both parts?
Both the 74LVC1G86SE-7 and 74LVCE1G86SE-7 are specified for the industrial temperature range of -40 °C to +85 °C, and both are also available in an extended -40 °C to +125 °C range depending on the ordering option.
Are these devices RoHS compliant and halogen-free?
Yes. Both the 74LVC1G86SE-7 and 74LVCE1G86SE-7 are RoHS compliant and halogen-free, as stated in the Diodes Incorporated datasheets and product compliance documentation.
