ISL3178AEMBZ-T

Overview

The ISL3178AEMBZ-T is a half-duplex RS-485/RS-422 transceiver in an 8-lead SOIC package. It operates on a single 3.0V to 3.6V supply with a maximum data rate of 10Mbps and quiescent current up to 800µA. The device features ±15kV IEC61000 ESD protection, full fail-safe receivers, and hot-plug capability. It presents a true 1/8 unit load, supporting up to 256 devices on the bus. Shutdown current is 10nA, and it functions within a -55°C to +125°C temperature range.

Feature Summary

IEC61000 ESD protection on RS-485 I/O pins
Full fail-safe receiver design
Hot plug functionality during power-up
True 1/8 unit load for high node counts

Applications

Automated utility meter reading systems
High node count systems
Field bus networks
Security camera networks
Building environmental control/lighting systems

Procurement Notes

Verify the datasheet revision FN6887 Rev 3.00 and confirm the specific ordering suffix matches the required tape and reel configuration. Ensure the component meets RoHS compliance standards as specified in the manufacturer's documentation. Cross-reference the pinout and thermal characteristics against the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high node density due to its 1/8 unit load characteristic. Verify that the 10Mbps data rate aligns with system timing requirements. Confirm compatibility with the 3.3V supply voltage and ensure the 8-lead SOIC package fits the available board space constraints.

Part Context

This part belongs to the ISL317xE family of low-power, high-speed RS-485/RS-422 transceivers. It shares core architectural features with other members like the ISL3172E but differs in duplex mode and specific electrical parameters. The ISL3178AE is explicitly marked as not recommended for new designs by the manufacturer.
