Compared to the classic MAX232, it offers wider supply range, higher speed (250kbps), lower power (300\u00b5A), and requires smaller capacitors (0.1\u00b5F). The TSSOP-16 package suits space-constrained portable equipment.","working_principle":"Similar to MAX232 but with improved design. The charge pump generates RS-232 levels from 3-5.5V supply using only 0.1\u00b5F capacitors. Drivers convert TTL\/CMOS to RS-232 levels, receivers do the reverse. The CUE suffix specifies TSSOP-16 package, commercial temperature range (0-70\u00b0C).","pin_description":"
