The IL485-3V is a galvanically isolated, high speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. Isolation is achieved through patented* Isoloop® technology. The IL485-3V is the first isolated RS-485 interface available in a standard 16 pin SOIC package, which meets the ANSI Standards EIA/TIA-422-B and RS485 and is compatible with 3.3V input supplies.
The IL485-3V has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations where these may cause excessive power dissipation.
With 1 nsec pulse skew and 16 nsec propagation delay, the IL485 is ideal for PROFIBUS applications.

The IL485W has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations where these may cause excessive power dissipation.
With a 1 nsec pulse skew and 16 nsec propagation delay, the IL485W is ideal for PROFIBUS applications. Use of DE/ISODE and IN1/OUT1 allows the IL485W to perform the handshaking operations of RTSAS and DTSAS of PROFIBUS.

The IL494 incorporates on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control circuit. Designed primarily for power supply control, the IL494 contains an on-chip 5-volt regulator, two error amplifiers, adjustable oscillator, dead-time control comparator, pulse-steering flip-flop, and output-control circuitry. The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Push-pull or single-ended output operation may be selected through the outputcontrol function. The architecture of the IL494 prohibits the possibility of either output being pulsed twice during push-pull operation.
