ISL3156EIBZ-T7A

Overview

The ISL3156EIBZ-T7A is a low-power RS-485/RS-422 differential transceiver manufactured by Renesas Electronics. It operates on a single 5 V supply and supports data rates up to 20 Mb/s. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It includes a full-fail-safe receiver that guarantees a high output when the inputs are open or undriven. The component is housed in an SOIC-14 surface-mount package and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• IEC 61000-4-2 ESD protection for robust operation in electrically noisy environments
• Full-fail-safe receiver ensures a defined high logic state during input disconnection
• Low quiescent current consumption with shutdown mode capability
• Supports half-duplex communication over twisted-pair transmission lines

Applications

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

Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the supplier provides traceability for the Renesas Electronics Corporation origin. Validate the SOIC-14 package dimensions against standard JEDEC specifications prior to integration.

Selection Notes

Select this component for applications requiring high-speed differential signaling up to 20 Mb/s with integrated ESD protection. Compare against similar models like the ISL3155E or ISL3158E based on required driver/receiver counts and voltage levels. Ensure the system design accommodates the 5 V supply requirement and the thermal characteristics of the SOIC-14 package.

Part Context

This part belongs to the ISL315xE series of RS-485/RS-422 transceivers from Renesas. The series is designed for industrial applications requiring reliable communication over long distances. The ISL3156 variant specifically offers a single driver and single receiver configuration in a 14-pin package, distinguishing it from smaller 8-pin alternatives.

Replacement Considerations

ISL3156EIBZ: Identical electrical specifications without reel packaging. ISL3155EIBZ-T7A: Similar performance but may differ in pinout or specific ESD ratings; verify datasheet compatibility before substitution.
