Sp3232+vs+max3232+exclusive ((new)) Page

Both devices are marketed as "low power," but the MAX3232 often demonstrates slightly better efficiency in sleep modes or during high-speed data transitions.

Always verify the . While both chips generally use 0.1µF, some older clones or specific variants of the 3232 family might require 1.0µF for stable charge pump operation at 3.3V. Check your specific manufacturer’s datasheet before freezing your PCB layout. sp3232+vs+max3232+exclusive

At exactly 3.0V, the MAX3232’s output voltage swing drops to ±3.7V—marginally above the RS-232 minimum (±3V). The SP3232E maintains a at 3.0V due to its improved MOSFET switch resistance. Both devices are marketed as "low power," but
