Interface Products

Intersil offers industry-leading devices to enable efficient and reliable communication for industrial control, networking, and computing applications. Dual protocol transceivers, voltage level translators, I2C Buffers, wide operating voltage range RS-232 transceivers, and RS-485/422 devices with the highest noise immunity and ESD protection in small packages are available to support high-speed data transfer and a variety of configurations to fit your application.

RS-485 and RS-422
Intersil has a broad portfolio of half duplex and full duplex RS-485 transceivers in a variety of speed grades to address any application needing reliable data transmission over twisted pair wiring. From low cost to robust, 3.3V or 5V and even down to 1.8V operation, Intersil has the perfect transceiver to meet demanding communication requirements.
Intersil has a rich history of developing innovative RS-232 protocol devices. Options include data rates to 1Mbps, IEC61000 ESD protection, low power shut down modes, and small QFN packages. Parts come in many transmit and receive configurations to meet all possible end equipment requirements.
2-Wire Bus Buffers
Intersil's 2-Wire Bus Buffers are designed to improve data transmission speed on SMBus or similar 2-wire serial bus interfaces. The ISL3300x I2C bus buffer family overcomes high capacitive load to ensure data integrity. Long connecting lines can exceed the 400pF max capacitive load specified by the I2C protocol. On board accelerators will overcome this load and deliver a reliable signal.
Signal Integrity Products
The rapid development of multimedia communications creates a need for ever-increasing data throughput. As line rates over 10 Giga-bit-per-second, passive copper cabling will not support links over more a few meters, Intersil’s Signal Integrity Product with Q-Active Technology provides a 300% reach extension over passive copper solutions at the same time consuming 80% less power than competing optical solutions.
