ISL3180EIBZ

Overview

The ISL3180EIBZ is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates on a 3V to 3.6V supply voltage with a typical operating current of 4 mA at 3.3 V. The device supports data rates up to 40 Mb/s and functions within an ambient temperature range of -40°C to +85°C. Packaged in a 14-pin SOIC (SOIC-14) surface-mount format, it provides one driver and one receiver. The component features ESD protection and includes shutdown functionality for power management.

Feature Summary

• High electrostatic discharge (ESD) protection capabilities integrated into the design
• Full fail-safe receiver operation ensuring defined logic states during floating or undriven conditions
• Low bus current consumption allowing connection of up to 160 transceivers on a single network without repeaters
• Hot plug circuitry maintains high impedance outputs during power supply stabilization

Applications

• Motor controller and position encoder systems
• Factory automation and field bus networks
• Security networks and building environmental control systems
• Industrial and process control networks

Procurement Notes

Verify the specific package variant against official datasheets, as the IBZ suffix typically denotes lead-free tape-and-reel packaging while non-suffixed parts may differ. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure the selected component matches the required 14-pin SOIC footprint and thermal specifications for the target application environment.

Selection Notes

Select this component for full-duplex applications requiring high-speed communication up to 40 Mb/s. The low unit load characteristic makes it suitable for extensive multi-drop networks exceeding standard RS-485 limits. Verify that the 3.3V nominal supply aligns with system power rails and that the 14-pin package fits the available PCB real estate constraints.

Part Context

This part belongs to the ISL3180E series of high ESD protected transceivers designed for balanced communication standards. It complements half-duplex variants like the ISL3179E by offering dedicated transmit and receive paths. The series emphasizes robustness in noisy industrial environments through advanced fail-safe and hot-plug features.

Replacement Considerations

Direct functional substitutes include other single RS-485/RS-422 transceivers with comparable 40 Mb/s speeds and 3.3V operation. Verify pin compatibility and package dimensions before substitution. Cross-reference specific ESD ratings and fail-safe thresholds to ensure equivalent performance in critical signal integrity scenarios.
