The 2µA maximum quiescent current keeps static power negligible in battery-backed or power-sensitive designs.
It is ROHS3 compliant. There is no end-of-life notice or last-time-buy risk for this part. For BOM planning, this gate is a stable, long-availability choice for 5V logic designs.
The CD74HCT86M has TTL-compatible input thresholds (0.8V low, 2V high) for direct interface with 5V TTL logic, while the CD74HC86M uses standard CMOS thresholds (typically 0.3xVCC low, 0.7xVCC high). Both are quad 2-input XOR gates in the same package, but the HCT variant is preferred when mixing with TTL families.
A 74HC86 is functionally equivalent (quad 2-input XOR) and pin-compatible in the same 14-SOIC package, but uses CMOS input thresholds instead of TTL-compatible thresholds. If your system already uses 5V CMOS logic, the 74HC86 works; if you need TTL compatibility, stick with the CD74HCT86M.
Yes, the CD74HCT86M is ROHS3 compliant.
