ISL3178EIBZ

Drivers, Receivers, Transceivers Overview

The ISL3178EIBZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 20 Mbps. The device features ±15kV IEC61000 ESD protection on the bus pins and >7kV HBM protection on other pins. It incorporates full fail-safe receiver inputs, hot-plug capability, and true 1/8 unit load characteristics allowing up to 256 nodes. Operating temperature ranges from -40°C to +85°C with a maximum quiescent current of 800µA.

Drivers, Receivers, Transceivers Feature Summary

• IEC61000 ESD protection on RS-485 I/O pins
• Full fail-safe receiver design for floating or shorted inputs
• Hot-plug circuitry maintaining three-state outputs during power-up
• True 1/8 unit load enabling high node density

Drivers, Receivers, Transceivers Applications

• Remote utility meter reading systems
• Industrial automation networks
• Building automation control systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IBZ-T' against official datasheets to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering code matches the exact package variant required for the PCB footprint. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and traceability before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-485 networks requiring high node counts due to its 1/8 unit load specification. It is suitable for environments demanding robust ESD immunity without external protection components. Verify that the 3.3V supply voltage aligns with the system's power architecture and that the SOIC-8 package fits the available board space constraints.

Drivers, Receivers, Transceivers Part Context

This device belongs to the ISL317xE series of low-power, high-speed transceivers. The series includes variants like the ISL3172E and ISL3175E, which share similar electrical characteristics but may differ in driver slew rate limitations or duplex configurations. All members support the same 3.3V operation and ESD protection standards.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes within the ISL317xE family such as ISL3172EIBZ or ISL3175EIBZ. Confirm pinout compatibility and functional equivalence regarding half/full duplex requirements before substitution.
