ISL3176EIUZ

Overview

The ISL3176EIUZ is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply and supports data rates up to 20 Mb/s. The device features ±15kV IEC61000 ESD protection and offers a common-mode input/output voltage range of -7V to +12V. It draws a maximum quiescent current of 800µA and reduces to 10nA in shutdown mode. Packaged in an MSOP-10 surface-mount format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Full fail-safe receiver design ensures logic high output when inputs are floating, shorted, or undriven.
• Hot plug circuitry maintains three-state outputs during power-up to prevent bus contention.
• True 1/8 unit load capability allows connection of up to 256 devices on the network without repeaters.

Applications

• Remote utility meter reading systems
• High node count field bus networks
• Security camera networks

Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation, as standard listings typically reference 'ISL3176EIUZ'. Confirm RoHS compliance status and package integrity upon receipt. Ensure the component matches the MSOP-10 footprint and pinout specifications defined in the datasheet before integration into the PCB layout.

Selection Notes

Select this component for applications requiring robust ESD protection and high noise immunity in harsh environments. The true 1/8 unit load specification makes it suitable for multi-drop networks with extensive node counts. Verify that the 3.3V supply voltage aligns with the system's power architecture and that the MSOP-10 package fits the available board space constraints.

Part Context

This part belongs to the ISL317xE family of low-power, high-speed RS-485/RS-422 transceivers. The family shares core features such as full fail-safe receivers and hot plug capabilities. Variants within the series differ primarily in driver slew rate limitations and duplex configuration (half vs. full).

Replacement Considerations

Cross-reference with other ISL317xE variants like ISL3172E or ISL3177E if different slew rates or package options are required. Ensure any substitute maintains the same 3.3V operation and MSOP-10 footprint for direct compatibility.
