ISL3159EFRZ-T

Overview

The ISL3159EFRZ-T is a low-power RS-422/RS-485 transceiver manufactured by Renesas Electronics. It integrates one driver and one receiver, supporting half-duplex communication with a data rate of 40 Mb/s. The device operates on a single 5 V supply and features a shutdown mode to minimize power consumption. It is housed in an 8-lead SOIC package and is rated for operation within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed data transmission up to 40 Mb/s over differential bus lines.
• Integrates a shutdown control pin to significantly reduce quiescent current during idle periods.
• Provides robust protection against electrostatic discharge and bus fault conditions.

Applications

• Industrial automation networks requiring reliable serial communication.
• Building automation systems utilizing RS-485 bus topologies.
• Metering applications such as electricity and gas meters.

Procurement Notes

Verify the specific suffix 'EFRZ' against the manufacturer's official documentation to confirm the exact temperature grade and tape-and-reel packaging configuration. Ensure that the ordering information matches the required operational temperature range and delivery format specifications before finalizing procurement.

Selection Notes

Select this component when a single half-duplex transceiver with 40 Mb/s capability is required. It is suitable for designs needing low standby power via shutdown mode. Verify compatibility with the system's 5 V logic levels and ensure the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISL3159E series of RS-422/RS-485 interface ICs. The series is designed for noisy environments, offering common-mode rejection and fault protection. The 'T' suffix indicates tube packaging, while 'EFRZ' specifies the extended temperature range and reel variant.

Replacement Considerations

Check for direct replacements within the ISL3159 family or compatible RS-485 transceivers from other manufacturers. Ensure pinout compatibility and identical electrical characteristics, particularly data rate and supply voltage, before substituting.
