ICL3310IB-T

Overview

The Intersil ICL3310IB-T is a full-duplex RS-232 transceiver designed for low-power applications. It operates within a supply voltage range of 3.0V to 5.5V, supporting data rates up to 250kbps while consuming only 1 microampere in standby mode. The device integrates two drivers and two receivers, housed in an 18-SOIC package. It meets EIA/TIA-232 and V.28/V.24 specifications at the minimum supply voltage. Key electrical characteristics include a receiver hysteresis of 500mV and protection against ±15kV electrostatic discharge (ESD).

Feature Summary

• Ultra-low standby current consumption of 1 microampere for extended battery life.
• Integrated ±15kV ESD protection on all RS-232 signal pins.
• Direct interfacing capability with 3.3V logic systems without level shifting.
• Compliance with EIA/TIA-232 and V.28/V.24 standards at 3.0V operation.

Applications

• Interfacing 3.3V microcontrollers with legacy RS-232 peripherals.
• Portable battery-powered communication devices requiring low power.
• Industrial control systems needing ESD-protected serial links.
• Embedded systems with space constraints utilizing SOIC packaging.

Procurement Notes

Verify the manufacturer marking matches Intersil or Renesas Electronics Corporation. Confirm the suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Check the date code for authenticity and storage conditions. Ensure the 18-SOIC pinout aligns with the specific datasheet revision used in design. Request lot traceability documentation for critical industrial or medical deployments.

Selection Notes

Select this component when designing systems that require direct 3.3V interface to RS-232 without external charge pumps. It is suitable for applications prioritizing low standby power over high-speed data transmission. Consider the 18-SOIC footprint for PCB layout constraints. Verify that the 250kbps maximum data rate meets the system's throughput requirements. Evaluate the need for ±15kV ESD protection based on the operating environment.

Part Context

The ICL3310 belongs to the Intersil ICL33xx family of low-power RS-232 transceivers. This series is engineered for portable electronics where power efficiency is critical. The IB-T variant specifically denotes the industrial temperature range and tape-and-reel delivery format. It complements other parts in the family offering different driver/receiver counts or package options.

Replacement Considerations

Public confirmed substitutes include the ICL3310CB-T and ICL3310IB. These variants share identical electrical specifications and functionality. Verify package compatibility and temperature range ratings before substitution. Cross-reference pinouts to ensure mechanical interchangeability in existing designs.
