DATASHEET
ISL8483E, ISL8485E FN6048
Rev.12.00
Aug 31, 2017 ESD Protected to В±15kV, 5V, Low Power, High Speed or Slew Rate Limited
RS-485/RS-422 Transceivers
The ISL8483E and ISL8485E are ESD protected, BiCMOS 5V
powered, single transceivers that meet both the RS-485 and
RS-422 standards for balanced communication. Each driver
output/receiver input is protected against В±15kV ESD strikes,
without latch-up. Unlike competitive devices, this Intersil
family is specified for 10% tolerance supplies (4.5V to 5.5V).
The ISL8483E uses slew rate limited drivers which reduce EMI
and minimize reflections from improperly terminated
transmission lines or unterminated stubs in multidrop and
multipoint applications.
Data rates up to 10Mbps are achievable by using the
ISL8485E, which features higher slew rates. Features Pb-Free (RoHS compliant) Extended industrial temperature options (+125В°C) RS-485 I/O pin ESD protection В±15kV HBM
-Class 3 ESD level on all other pins . >7kV HBM Specified for 10% tolerance supplies High data rate version (ISL8485E) up to 10Mbps Slew rate limited version for error free data transmission
(ISL8483E) . up to 250kbps Single unit load allows up to 32 devices on the bus Both devices present a “single unit load” to the RS-485 bus,
which allows up to 32 transceivers on the network. 1nA low current Shutdown mode (ISL8483E) Receiver (Rx) inputs feature a “fail-safe if open” design, which
ensures a logic high Rx output if Rx inputs are floating. Low quiescent current:
-160ВµA (ISL8483E)
-500ВµA (ISL8485E) Driver (Tx) outputs are short-circuit protected, even for voltages …
