DATASHEET ISL8483E, ISL8485E FN6048 Rev.13.00 ESD Protected to 15kV, 5V, Low Power, High Speed or Slew Rate Limited Sep 24, 2018 RS-485/RS-422 Transceivers The ISL8483E and ISL8485E are ESD protected, BiCMOS 5V Features powered, single transceivers that meet both the RS-485 and Pb-Free (RoHS compliant) RS-422 standards for balanced communication. Each driver output/receiver input is protected against 15kV ESD strikes Extended industrial temperature options (+125C) without latch-up. Unlike competitive devices, this Renesas RS-485 I/O pin ESD protection 15kV HBM family is specified for 10% tolerance supplies (4.5V to 5.5V). - Class 3 ESD level on all other pins . >7kV HBM The ISL8483E uses slew rate limited drivers that reduce EMI Specified for 10% tolerance supplies and minimize reflections from improperly terminated transmission lines or unterminated stubs in multidrop and High data rate version (ISL8485E) up to 10Mbps multipoint applications. Slew rate limited version for error free data transmission (ISL8483E) . up to 250kbps Data rates up to 10Mbps are achievable by using the ISL8485E, which features higher slew rates. Single unit load allows up to 32 devices on the bus Both devices present a single unit load to the RS-485 bus, 1nA low current Shutdown mode (ISL8483E) which allows up to 32 transceivers on the network. Low quiescent current: Receiver (Rx) inputs feature a fail-safe if open design, which - 160A (ISL8483E) ensures a logic high Rx output if Rx inputs are floating. - 500A (ISL8485E) Driver (Tx) outputs are short-circuit protected even for voltages -7V to +12V common-mode input voltage range exceeding the power supply voltage. Additionally, on-chip Three-state Rx and Tx outputs thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive. 30ns propagation delays, 5ns skew (ISL8485E) Operate from a single +5V supply (10% tolerance) These half duplex configurations multiplex the Rx inputs and Tx outputs to allow transceivers with Rx and Tx disable Current limiting and thermal shutdown for driver overload functions in 8 Ld packages. protection Related Literature Applications For a full list of related documents, visit our website: Factory automation ISL8483E and ISL8485E product pages Security networks Building environmental control systems Industrial/process control networks Level translators (such as RS-232 to RS-422) RS-232 extension cords TABLE 1.

Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in reflow solder processing applications. 2. Refer to TB347 for details about reel specifications. 3. These Pb-free plus anneal products employ special Pb-free material sets molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 4. For Moisture Sensitivity Level (MSL), refer to the product information pages for the ISL8483E and the ISL8485E. For more information on MSL, refer to TB363. FN6048 Rev.13.00 Page 2 of 15 Sep 24, 2018
