The MAX3318E is a dual-driver, dual-receiver, RS-232-compatible transceiver. The device features auto-power-down plus and enhanced electrostatic discharge (ESD) protection integrated into the chip. Driver output and receiver input are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model (HBM). The device operates at a data rate of 460 kbps. The transceiver has a proprietary low-dropout driver output stage, enabling RS-232-compatible operation from a 2.25-V to 3-V supply with a dual charge pump. The charge pump require
The MAX3318E is a dual‑driver, dual‑receiver RS‑232‑compatible transceiver designed for low‑power, battery‑powered applications. It operates from a single 2.25 V to 3 V supply and includes an auto‑power‑down plus feature that reduces supply current to 1 µA when the serial port is idle.
The device offers robust electrostatic discharge protection of up to +15 kV (human‑body model) and includes a charge‑pump architecture that requires only four 0.1 µF capacitors. It is available in 20‑pin SSOP and 20‑pin TSSOP packages.
