Quad 2-input XOR in 14-SSOP — what it does and where it fits
The Texas Instruments SN74LVC86ADBR is a quad 2-input XOR gate from the 74LVC logic family, packaged in a 14-SSOP (5.30 mm width) for surface-mount assembly. It operates from a 1.65 V to 3.6 V supply, with four independent XOR gates each sinking or sourcing 24 mA, and a propagation delay of 4.4 ns at 3.3 V and 50 pF load. The -40°C to 125°C temperature range qualifies it for industrial and automotive under-hood environments.
Supply range and timing — the BOM-fit details
The 1.65 V to 3.6 V supply range means this gate works directly on a 1.8 V FPGA I/O bank or a 3.3 V microcontroller port without extra regulators. The 4.4 ns propagation delay at 3.3 V is fast enough for 50–100 MHz bus-level glue logic; at 1.8 V the delay increases (per the family curve) but remains within a typical 8–10 ns window for slower interfaces like I2C or GPIO expansion. Quiescent current is a maximum of 1 µA, so the static power contribution is negligible even in battery-powered designs that spend most of their time in sleep.
