MAX3314EEUA+

产品概述

The MAX3314EEUA+ from Maxim Integrated Products is a ±15KV ESD protected RS232 compatible transceiver in 8 pin µMAX package. This ±5V powered EIA/TIA-232 compatible interface has one transmitter and one receiver in a flow through architecture. The transmitter output and the receiver input are protected to ±15KV using IEC 1000-4-2 air gap discharge, ±8KV using IEC 1000-4-2 contact discharge and ±15KV using human body model (HBM). The transmitter has low dropout output stage providing minimum RS232 compatible ±3.7V output levels while driving 3Kohm and 1000pF at 460Kbps. Both +5V and -5V must be supplied externally. The MAX3314E has a active-low SHDN function that reduces supply current to 1µA. The transmitter is disabled and put into tri-state while the receiver remains active. Typical application includes digital cameras, PDAs, GPS, POS, telecommunications, handy terminals and set-top boxes.
