The MAX3384E is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements, high data-rate capabilities, and en- hanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The transceiver has a proprietary low-dropout transmit- ter output stage, delivering true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump requires only four small 0.1µF capac- itors for operation from a +3.3V supply. Each device is guaranteed to run at data rates of 250kbps while main- taining RS-232 output levels. The MAX3384E has two receivers and two drivers. It features a 1µA shutdown mode that reduces power con- sumption and extends battery life in portable systems. The MAX3384E is available in a space-saving SSOP package in either the commercial (0°C to +70°C) or extended temperature (-40°C to +85°C) range.
The MAX3384E is a 3 V‑powered EIA/TIA‑232 and V.28/V.24 communications interface featuring low power consumption, high data‑rate capability, and robust ESD protection. It operates from a 3.0 V to 5.5 V supply, provides true RS‑232 voltage levels, and includes a dual charge‑pump for ±5.5 V output.
The device is offered in a space‑saving SSOP package, available in commercial (0 °C to +70 °C) and extended (‑40 °C to +85 °C) temperature ranges. It includes a 1 A shutdown mode that reduces supply current to microamp levels, and its pins are protected to +15 kV (HBM), +8 kV (IEC contact) and +15 kV (IEC air‑gap).
