FEATURES
➢ 5V power supply, half-duplex ➢ 1/8 unit loads, allow up to 256 transceivers on the bus ➢ Short-circuit protection ➢ Overtemperature protection ➢ Low power off function ➢ /RE, DE ports allow hot plug input ➢ Receiver open-circuit failure protection； ➢ Strong anti-noise ability ➢ Integrated transient voltage suppression ➢ 32-node communication rate up to 2.5Mbps ➢ A, B ports protection: contact discharge ±15kV; HBM±15kV PRODUCT APPEARANCE Provide environmentally friendly lead-free package DESCRIPTION
SIT485E includes a driver and a receiver, both of which can be enabled and closed independently. Using a voltage-limited slew rate driver can significantly reduce EMI and reflections due to improper termination matching cabling. 32 nodes can achieve 2.5Mbps communication rate. SIT485E has a working voltage range of 4.75~5.25V, and has the functions of fail-safe, current-limiting protection, over-voltage protection, hot plug input of control port, etc. SIT485E has excellent ESD discharge capability, HBM reaches ± 15kV, contact discharge, IEC61000-4-2 ± 15kV.
