Rev.3.00
Mar 29, 2017 Ultra-Low EMI, Smallest Package Isolated RS-485 Transceiver
The ISL32704E is a galvanically isolated, differential bus
transceiver designed for bidirectional data transmission and
meeting the RS-485 and RS-422 standards for balanced
communication. Each of the bus terminals, A and B, is
protected against ±15kV ESD strikes without latch-up. Features The device uses Giant Magnetoresistance (GMR) as isolation
technology. A unique ceramic/polymer composite barrier
provides excellent isolation and virtually unlimited barrier life. • 3V to 5V power supplies The part is available in a 16 Ld QSOP package offering
unprecedented miniaturization, and in a 16 Ld wide-body SOIC
package providing true 8 millimeter creepage distance. • 4Mbps data rate
• 2.5kVRMS isolation per UL 1577
• 600VRMS working voltage per VDE 0884
• Single unit load receiver input
• Driver drives up to 150 unit loads
• 50kV/µs (typical), 30kV/µs (minimum) common-mode
transient immunity The ISL32704E delivers a minimum differential output voltage
of 1.5V into a 54Ω differential load for excellent data integrity
over long cable lengths. • 44000 years barrier life The device is compatible with 3V and 5V input supplies,
allowing interface to standard microcontrollers without
additional level shifting. • -40°C to +85°C temperature range Current limiting and thermal shutdown features protect …
