Exhibits a slightly higher internal output impedance under low VCCcap V sub cap C cap C end-sub
Design Note: Regardless of the chip chosen, it is best practice to tie unused logic inputs to either VCCcap V sub cap C cap C end-sub sp3232+vs+max3232+exclusive
Neither the MAX3232 nor the SP3232 is universally "better." They are two solutions optimized for different design priorities. The MAX3232 excels in environments demanding — three attributes that matter greatly in industrial, automotive, and medical applications. The SP3232 shines as the cost‑effective, space‑saving workhorse for high‑volume consumer goods, compact devices, and projects where budget constraints are paramount.

The SP3232 layout is tightly bounded to prevent cross-talk when inputs are tri-stated or left un-driven by the primary micro-controller (MCU). The SP3232 layout is tightly bounded to prevent
