ISL3175EIBZ-T

Overview

The ISL3175EIBZ-T is a low-power, half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3V to 3.6V and supports data rates up to 500kbps. The device features integrated IEC 61000-4-2 electrostatic discharge (ESD) protection rated at ±15kV for air discharge and ±8kV for contact discharge. Packaged in an 8-pin SOIC surface-mount format, it includes one driver and one receiver with differential outputs and inverted inputs. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated high-level ESD protection compliant with IEC 61000-4-2 standards
• Low power consumption suitable for battery-operated applications
• Half-duplex operation with differential output capability

Applications

• Industrial communication networks requiring robust ESD immunity
• Building automation systems utilizing RS-485 bus topology
• Metering equipment operating on limited power supplies

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Renesas or Intersil depending on the production lot. Ensure the order matches the exact part number ISL3175EIBZ-T to guarantee correct package type and electrical specifications.

Selection Notes

Select this component for designs requiring 3V operation with moderate speed requirements. It serves as a direct replacement for legacy Intersil RS-485 parts. Verify that the system environment does not exceed the specified 3.6V maximum supply voltage limit during transient conditions.

Part Context

This part belongs to the ISL3175E series of RS-485 interface devices. It represents a transition product following Renesas's acquisition of Intersil. The component maintains compatibility with standard RS-485 protocols while offering enhanced protection features compared to earlier generations.

Replacement Considerations

Direct pin-compatible alternatives include the ISL3175EIBZ without the trailing T if loose tube packaging is preferred. Other family members like the ISL3172E offer similar functionality but may differ in specific electrical parameters or feature sets.
