ICL3226ECAZ-T

Overview

The ICL3226ECAZ-T is a single-driver, single-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features an automatic power-down function that reduces standby current to approximately 1 mA when the interface is idle. It provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is housed in a 16-pin SSOP package and is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Automatic power-down circuitry activates during idle periods to minimize standby power consumption.
• Integrated charge pumps enable operation from a single 3 V to 5.5 V supply without external components.
• Robust 15 kV ESD protection is provided on all RS-232 signal lines.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems with serial communication interfaces
• Embedded devices connecting to PC serial ports

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging distinct from tube variants. Confirm the 'E' designation corresponds to the extended temperature or specific protection grade relative to non-E counterparts. Check RoHS compliance status directly against the manufacturer's latest documentation before procurement.

Selection Notes

Select this component for applications requiring full-duplex RS-232 communication with minimal quiescent current. Ensure the system voltage remains within the 3 V to 5.5 V range. Verify that the 250 kb/s data rate meets the application requirements, as higher-speed variants exist within the family.

Part Context

This part belongs to the ICL3226 series of low-power RS-232 transceivers. It shares functional similarities with the ICL3226CAZ but includes enhanced protection features indicated by the 'E' suffix. The 'T' suffix specifies reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

The ICL3226CAZ serves as a direct pin-compatible alternative if tube packaging is acceptable. Other members of the ICL32xx family may offer different driver/receiver counts or speed capabilities but require schematic verification.
