ICL3245ECAZ-T

Overview

The ICL3245ECAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics. It operates on a single +3V to +5.5V supply and supports data rates up to 1 Mb/s. The device integrates three drivers and five receivers in a full-duplex configuration. It features enhanced automatic powerdown functionality, reducing quiescent current to approximately 1 µA during shutdown. The component provides 15 kV ESD protection on RS-232 lines and is housed in an SSOP-28 package suitable for surface mount applications.

Feature Summary

• Enhanced automatic powerdown mechanism significantly reduces power consumption when the interface is idle.
• Integrated charge pump circuitry eliminates the need for external capacitors for voltage generation.
• Robust electrostatic discharge protection ensures reliability in high-interference environments.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems with RS-232 communication interfaces
• Medical instrumentation utilizing serial data transmission

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging rather than tube packaging. Confirm the specific manufacturer lot codes against official Renesas documentation to ensure authenticity. Check for moisture sensitivity level compliance prior to soldering processes.

Selection Notes

Select this component when a combination of three transmit and five receive channels is required within a single IC. It is appropriate for designs prioritizing low power consumption through automatic shutdown features while maintaining compatibility with standard RS-232 signaling levels.

Part Context

This part belongs to the ICL3245E series of RS-232 transceivers. It shares functional similarities with other members of the family but is distinguished by its specific driver and receiver count configuration. The 'ECAZ' designation typically denotes commercial temperature range and lead-free construction.

Replacement Considerations

Direct pin-compatible alternatives may include the ICL3245CA or ICL3245EC variants, depending on packaging requirements. Verify that substitute parts maintain the same 1 Mb/s data rate and 15 kV ESD protection specifications before implementation.
