ICL3232IB-T

Overview

The ICL3232IB-T is a dual driver, dual receiver RS-232 transceiver manufactured by Intersil. It operates on a single 3 V to 5.5 V supply and achieves data rates up to 250 kb/s. The device features full-duplex communication with 15 kV ESD protection on all pins. It utilizes external charge pumps for voltage generation and draws only 1 mA of supply current. The component is housed in a SOIC-Narrow-16 surface-mount package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external positive and negative voltage sources.
• Provides robust electrostatic discharge protection rated at 15 kV across all signal interfaces.
• Maintains low power consumption through a dedicated 1 mA operating current specification.

Applications

• Industrial serial communication equipment requiring reliable RS-232 connectivity
• Portable battery-operated devices utilizing low-voltage logic interfaces
• Data acquisition systems interfacing microcontrollers with standard serial ports

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the ordering code matches the required tape-and-reel configuration for automated assembly processes. Cross-reference the part number with the latest datasheet revision to validate active status and compliance details before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require dual-channel RS-232 transmission within a limited power budget. The SOIC-16 package offers a compact footprint suitable for space-constrained printed circuit board layouts. Confirm that the system environment falls within the specified industrial temperature range and voltage constraints during the initial design phase.

Part Context

This device belongs to the ICL3232 series of RS-232 interface integrated circuits produced by Intersil, now part of Renesas Electronics. The series is characterized by its compatibility with standard RS-232 protocols and its ability to operate efficiently from a single low-voltage power supply without complex external biasing networks.

Replacement Considerations

Direct substitutes include the ICL3232IBNZ and ICL3232EIV-16Z. Verify pinout compatibility and electrical specifications against the target application requirements before implementing any alternative components in the design.
