ISL3177EIBZ

Drivers, Receivers, Transceivers Overview

The ISL3177EIBZ 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 Mb/s. The device features ±15kV IEC61000 ESD protection and full fail-safe receiver inputs that ensure a logic high output when inputs are floating, shorted, or undriven. It presents a true 1/8 unit load, allowing up to 256 devices on the bus without repeaters. Key electrical parameters include a maximum quiescent current of 800 µA and an ultra-low shutdown current of 10 nA. The operating temperature range spans from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Full fail-safe receiver design ensures defined logic states during open, short, or floating input conditions.
• Hot plug circuitry maintains Tx and Rx outputs in a high impedance state during power-up stabilization.
• Slew rate limited drivers reduce electromagnetic interference (EMI) and minimize signal reflections.

Drivers, Receivers, Transceivers Applications

• Remote utility meter reading systems
• High node count field bus networks
• Security camera networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EIBZ' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper handling. Confirm lead availability and production status directly with authorized distributors or the manufacturer.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed communication up to 20 Mb/s with low power consumption. The 1/8 unit load capability is critical for networks exceeding standard RS-485 node limits. Verify compatibility with 3.3V logic levels and ensure the SOIC-8 package fits the board layout constraints.

Drivers, Receivers, Transceivers Part Context

The ISL3177EIBZ belongs to the ISL317xE family of transceivers designed for balanced communication standards. This series includes both half-duplex and full-duplex variants. The ISL3177E specifically offers full duplex operation with separate receive and transmit pins within an 8-lead package format.

Drivers, Receivers, Transceivers Replacement Considerations

Consult official substitution guides for compatible RS-485/RS-422 transceivers. Verify pinout compatibility and electrical parameter equivalence before replacing components in existing designs.
