ISL3158AE
±16.5kV ESD (IEC61000-4-2) Protected,
Large Output Swing, 5V, Full Fail-Safe, 1/8
Unit Load, RS-485/RS-422 Transceiver
The ISL3158AE is a BiCMOS, IEC61000 ESD protected, 5V
powered, single transceiver that meets both the RS-485 and
RS-422 standards for balanced communication. Each driver
output and receiver input is protected against ±16.5kV ESD
strikes without latch-up.
The ISL3158AE transmitter delivers exceptional differential
output voltages (2.4V min), into the RS-485 required 54
Ω
load, for better noise immunity or to allow up to eight 120
Ω
terminations in “star” or other non-standard bus topologies.
This device has very low bus currents (+125A/-75A), so it
presents a true “1/8 unit load” to the RS-485 bus. This allows
up to 256 transceivers on the network without violating the
RS-485 specification’s 32 unit load maximum, and without
using repeaters.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which
ensures a logic high Rx output if Rx inputs are floating,
shorted, or on a terminated but undriven bus. Rx outputs
feature high drive levels - typically 28mA @ VOL = 1V (to
ease the design of optocoupled isolated interfaces).
Hot Plug circuitry ensures that the Tx and Rx outputs remain
in a high impedance state until the power supply has
stabilized, and the Tx outputs are fully short circuit protected.
The ISL3158AE is a half duplex version. It multiplexes the
Rx inputs and Tx outputs to allow transceivers with output
disable functions in an 8 Ld package.
