ISL3259EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL3259EIUZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It supports data rates up to 80 Mbps and operates on a single 5 V supply. The device integrates IEC 61000-4-2 ESD protection rated at ±15 kV for air discharge and ±8 kV for contact discharge. It features a fail-safe receiver that ensures a high logic state when inputs are open. The component is housed in an 8-lead MSOP package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated IEC 61000-4-2 electrostatic discharge protection for robust signal integrity
• Fail-safe receiver design maintains a defined high output state during idle conditions
• Low power consumption with dedicated shutdown mode for energy efficiency

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building automation systems
• Data acquisition modules

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging, distinct from tube variants. Confirm the manufacturer designation as Renesas or Intersil based on current corporate records. Ensure the order quantity aligns with the standard reel size requirements specified by authorized distributors.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 80 Mbps transmission speeds over RS-485 buses. It is suitable for environments demanding high ESD immunity without external protection components. Compare against lower-speed models like the ISL3159E if bandwidth requirements are less stringent.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3259E series of high-speed differential transceivers. It shares functional similarities with other half-duplex interface chips but is distinguished by its specific 80 Mbps speed rating and integrated ESD protection capabilities within the MSOP form factor.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL3259EIRZ serves as a pin-compatible alternative in a DFN-10 package. Verify thermal performance and pinout compatibility before substitution. Other series members may offer different speed ratings or packaging options.
