Maxim MAX3110E/MAX3111E Datasheet
The MAX3110E and MAX3111E combine a full‑featured UART with +15 kV ESD‑protected RS‑232 transceivers and internal charge‑pump capacitors in a 28‑pin package. They offer an SPI/QSPI/MICROWIRE‑compatible serial interface, low‑dropout output stage, and operate down to VCC = +3 V (MAX3111E) while consuming only 600 µA.
Typical applications include point‑of‑sale devices, handy terminals, telecom diagnostic ports, industrial front‑panel interfaces, and battery‑powered handheld equipment. The datasheet provides absolute maximum ratings, electrical characteristics, pin configuration, ordering information, and revision history.
