ISL8488E, ISL8489E, ISL8490E, ISL8491E FN6073
Rev.4.00
July 26, 2007 В±15kV ESD Protected, 5V, Low Power, High Speed and Slew Rate Limited, Full
Duplex, RS-485/RS-422 Transceivers
The ISL8488E, ISL8489E, ISL8490E, ISL8491E devices are
ESD protected, BiCMOS, 5V powered, single transceivers
that meet both the RS-485 and RS-422 standards for
balanced communication. Each driver output and receiver
input is protected against В±15kV ESD strikes, without
latch-up. Unlike competitive versions, these Intersil devices
are specified for 10% tolerance supplies (4.5V to 5.5V). Features RS-485 I/O Pin ESD Protection пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ пЂ®пЂ  п‚±15kV HBM

(ISL8488E, ISL8489E) These devices are configured for full duplex (separate Rx
input and Tx output pins) applications, so they are ideal for
RS-422 networks requiring high ESD tolerance on the bus
pins. The ISL8488E, ISL8490E are 8 Ld versions without Rx
and Tx output enables. The other two versions include Rx
and Tx output enable pins in a standard 14 Ld pinout. Single Unit Load Allows up to 32 Devices on the Bus
(See ISL4489E, ISL4491E for 256 Devices on Bus) Low Quiescent Current:
-120ВµA (ISL8488E)
-140ВµA (ISL8489E)
-370ВµA (ISL8490E, ISL8491E) The ISL8488E, ISL8489E utilize slew rate limited drivers …
