ICL3243ECVZA-T

Overview

The ICL3243ECVZA-T 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 3 V to 5.5 V. It utilizes a 28-pin TSSOP surface-mount package with a width of 4.40 mm. The component supports an operating temperature range from -40°C to +85°C and includes 15 kV ESD protection on all pins.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive serial communication control.
• Features automatic shutdown mode that reduces power consumption when no signal activity is detected.
• Provides robust electrostatic discharge protection rated at 15 kV across all interface pins.

Applications

• Industrial equipment requiring reliable RS-232 connectivity
• Portable battery-powered instruments utilizing low-power modes
• Modems and fax machines needing multi-channel transmission

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm if it denotes a specific tape-and-reel variant or packaging update distinct from standard listings. Confirm moisture sensitivity level (MSL) requirements prior to soldering to ensure proper storage handling. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status and lead times.

Selection Notes

Select this component when designing systems requiring multiple transmit and receive lines in a compact footprint. Ensure the application voltage remains within the 3 V to 5.5 V range to maintain signal integrity. Consider the 28-TSSOP package dimensions for PCB layout constraints. Verify that the 250 kbps speed meets the system's timing requirements compared to higher-speed alternatives.

Part Context

This part belongs to the ICL32xxE series of RS-232 transceivers, which are designed for low-voltage operation. The series typically includes variants like the ICL3243EIVZ-T, differing primarily in package type such as TSSOP versus SOIC. These components serve as direct replacements for legacy dual-supply RS-232 chips, simplifying power design in modern embedded systems.

Replacement Considerations

Check for ICL3243EIVZ-T as a potential alternative if package compatibility allows. Verify pin-to-pin equivalence with other ICL3243 variants before substitution. Ensure any replacement maintains the same driver/receiver count and voltage specifications.
