ISL3241EIRZ-T

Overview

The ISL3241EIRZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates one driver and five receivers, supporting data rates up to 500 kb/s. The device operates from a single 3 V to 5.5 V supply and includes an internal charge pump for voltage generation. Key electrical specifications include a quiescent current of 1 mA and ESD protection rated at 15 kV. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SSOP package.

Feature Summary

Integrates one driver and five receivers for multi-drop communication
Includes integrated charge pump eliminating external capacitors
Provides 15 kV ESD protection on all RS-232 pins

Applications

Industrial control systems requiring serial communication
Portable battery-powered equipment due to low power consumption
Multi-drop RS-232 networks utilizing multiple receivers

Procurement Notes

Verify the specific ordering suffix 'T' indicates reel packaging when sourcing components. Confirm that the manufacturer designation aligns with Renesas Electronics or Intersil legacy branding. Ensure the component meets RoHS compliance requirements for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component for designs requiring five receiver channels alongside a single driver. It is suitable for applications needing 500 kb/s throughput with minimal external passive components. Consider the SSOP-28 footprint constraints during PCB layout planning to ensure adequate spacing for the charge pump circuitry.

Part Context

This part belongs to the ICL3241 series of RS-232 interface ICs. It represents a transition product often associated with the Intersil brand prior to its acquisition by Renesas Electronics. The device serves as a direct replacement for older generations of low-power RS-232 transceivers in established industrial and commercial hardware designs.
