Overview
The ISL3243EIRZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates three drivers and five receivers within a single package, supporting data rates up to 250 kbps. The device operates on a single power supply ranging from 2.7 V to 3.6 V. It features ±15 kV ESD protection on all pins and includes automatic shutdown functionality for low-power applications. The component is housed in a 32-pin QFN package with an exposed pad, designed for surface-mount installation.
Feature Summary
- Integrates three independent drivers and five independent receivers for full RS-232 communication
- Provides robust ±15 kV electrostatic discharge (ESD) protection across all signal pins
- Incorporates automatic power-down mode to minimize current consumption during idle periods
- Supports common-mode voltage ranges of ±15 V for reliable operation in noisy environments
Applications
- Industrial control systems requiring isolated serial communication
- Portable battery-powered equipment utilizing low-voltage logic interfaces
- Data acquisition modules interfacing with RS-232 peripherals
- Embedded systems needing compact footprint solutions for serial I/O
Procurement Notes
Verify the specific suffix 'EIRZ' corresponds to the 32-pin QFN package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for any recent Product Change Notifications regarding labeling or assembly updates. Ensure the supplier provides valid traceability for the Renesas Electronics Corporation origin.
Selection Notes
Select this component when a full-duplex RS-232 interface is required with integrated ESD protection. It is suitable for designs constrained by a maximum supply voltage of 3.6 V. Consider the 32-pin QFN form factor for space-limited printed circuit board layouts. Verify that the 250 kbps data rate meets the system's throughput requirements.
Part Context
This part belongs to the ISL3243E family of RS-232 transceivers. It shares functional similarities with other members of the series but differs in package type and pin configuration. The 'E' designation typically indicates enhanced ESD protection capabilities compared to standard variants. It serves as a direct replacement for older Intersil-branded components in legacy designs.
