ISL8487EIBZ概述

INTERSIL  ISL8487EIBZ  收发器, RS422 / RS485, 4.5V-5.5电源, SOIC-8

The is an ESD protected fractional unit load BiCMOS Single Transceiver meets both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive devices, this family is specified for 10% tolerance supplies. The device presents a 1/8 unit load to the RS-485 bus, which allows up to 256 transceivers on the network for large node count systems. In a remote utility meter reading system, individual utility meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required to network all the meters. Data for all meters is then read out from the concentrator via a single access port or a wireless link. Slew rate limited driver on the ISL8487E reduces EMI and minimize reflections from improperly terminated transmission lines or un-terminated stubs in multi-drop and multipoint applications.
