ISL3153EIBZ-T7A

Overview

The ISL3153EIBZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 5 V supply and supports data rates up to 12 Mb/s. The device features IEC 61000-4-2 Level 4 ESD protection, rated at ±15 kV for air discharge and ±8 kV for contact discharge. It utilizes an SOIC-8 surface-mount package with a standard 1.27 mm pitch. The operational temperature range spans from -40 °C to +85 °C. Key electrical characteristics include a high-voltage differential output and low quiescent current.

Feature Summary

• Integrated IEC 61000-4-2 electrostatic discharge protection for robust signal integrity in harsh environments
• High-voltage differential output capability designed to ensure reliable communication over long bus lines
• Slew-rate limited driver output to minimize electromagnetic interference (EMI) during signal transitions

Applications

• Industrial automation control networks requiring noise immunity
• Building automation systems utilizing RS-485 bus topology
• Metering infrastructure for utility data collection

Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm that the component meets RoHS compliance requirements for the target market. Ensure the procurement source provides valid traceability records for this discontinued or legacy part number.

Selection Notes

Select this component when a 5 V supply voltage is required alongside high-speed data transmission capabilities up to 12 Mb/s. It is suitable for designs needing integrated ESD protection without external components. Consider alternative packages if board space constraints differ from the SOIC-8 footprint.

Part Context

This part belongs to the ISL315xE series of RS-422/RS-485 interface ICs. It shares functional similarities with other members like the ISL3152E but offers higher data rate performance. The series is characterized by ruggedized design features intended for industrial applications.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the ISL3152EIBZ-T7A. Verify compatibility regarding data rate differences and specific ESD protection levels before substitution.
