ICL3245ECVZ

Overview

The ICL3245ECVZ is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates three drivers and five receivers, supporting full-duplex communication at data rates up to 1 Mbps. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical quiescent current of 1 mA. It features enhanced automatic power-down functionality to minimize energy consumption during idle periods. The component provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. It is housed in a 28-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for multi-port serial communication.
• Features enhanced automatic power-down mode that reduces supply current to approximately 1 µA when inputs are unconnected or grounded.
• Provides robust 15 kV ESD protection on all RS-232 transceiver pins to safeguard against static discharge events.
• Operates reliably with a single 3 V to 5.5 V power supply, eliminating the need for external charge pumps.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable battery-powered equipment utilizing low-power RS-232 connectivity.
• Multi-drop serial communication networks involving multiple receivers.

Procurement Notes

Verify the specific suffix 'CVZ' corresponds to the TSSOP-28 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation. Ensure moisture sensitivity level handling procedures are followed during assembly. Cross-reference the part number with Renesas Electronics to confirm current production status and availability.

Selection Notes

Select this component when designing circuits requiring three transmit and five receive channels within a single IC. It is suitable for applications needing low standby power due to its automatic power-down feature. Choose this part over standard versions if industrial temperature ranges and ESD protection are critical requirements. Verify pin compatibility with existing PCB layouts designed for the ICL3245 family.

Part Context

The ICL3245ECVZ belongs to the ICL3245 series of RS-232 transceivers from Renesas Electronics. This series is known for combining high performance with low power consumption. The 'E' suffix typically denotes an extended industrial temperature range. The 'C' indicates the TSSOP package type, while 'VZ' often specifies lead-free and RoHS-compliant packaging variations within the manufacturer's catalog.

Replacement Considerations

Direct replacements include other ICL3245 variants with compatible packages and electrical specifications. Check for equivalent parts from Intersil or Renesas that maintain the 3-driver/5-receiver configuration. Ensure any substitute supports the same 1 Mbps data rate and 15 kV ESD protection levels. Verify thermal performance matches the original design constraints.
