ISL3159EFBZ-T7A

Overview

The ISL3159EFBZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates with a single 5 V supply and supports data rates up to 40 Mb/s. The device features a shutdown mode that reduces power consumption, with a typical operating supply current of 4 mA. It functions within an extended temperature range from -40 °C to +125 °C. The component is housed in an SOIC-8 surface-mount package and includes ESD protection compliant with IEC-61000 standards.

Feature Summary

• Supports high-speed data transmission up to 40 Mb/s over differential bus lines.
• Integrates robust electrostatic discharge (ESD) protection meeting IEC-61000 requirements.
• Includes a dedicated shutdown pin to minimize power usage during idle periods.

Applications

• Industrial automation control networks
• Building management systems
• Process instrumentation communication

Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when sourcing. Confirm the manufacturer as Renesas or Intersil to ensure authenticity. Check for RoHS compliance documentation if required by project specifications. Validate the SOIC-8 footprint against PCB design libraries before finalizing procurement orders.

Selection Notes

Select this component for applications requiring 5 V operation and high-speed RS-485 communication. Ensure the system environment supports the specified -40 °C to +125 °C operating temperature range. Verify that the half-duplex architecture aligns with the network topology requirements. Consider the SOIC-8 package size relative to available board space constraints.

Part Context

This part belongs to the ISL3159E series of RS-485 transceivers. The family includes variants with different packages such as DFN-EP-10 and tube-packaged versions like ISL3159EFBZ. All variants share core electrical characteristics including 40 Mb/s speed and 5 V supply voltage.

Replacement Considerations

Direct substitutes include ISL3159EFBZ (tube version) and ISL3159EIBZ (industrial temp). Cross-reference datasheets for pin compatibility and thermal performance differences between package types.
