Known for extremely low supply current, typically around 0.3mA (up to 1mA max) when unloaded.

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.

You need a slightly (up to 235kbps) without moving to a specialized high-speed chip.

You are building or hobbyist projects where "good enough" is perfect. 💡 Pro-Tip for Engineers

Slightly higher power draw, often idling around 1mA to 2mA . While still low, it is less efficient than the Maxim Integrated original in deep-sleep or idle states. 3. ESD Protection

You require reliability (Maxim’s testing protocols are historically more rigorous).

Here is the exclusive breakdown of how these two RS-232 transceivers stack up against each other. ⚡ The Core Functional Similarity

Budget is secondary to and long-term availability. Choose the SP3232 if:

Sipex/MaxLinear parts are almost always more affordable in high-volume production.
