ISL54103IHZ-T7

Overview

The ISL54103IHZ-T7 is a dual active pull-up bus terminator designed to accelerate data transmission on DDC 2-wire serial interfaces. It operates within a supply voltage range of 2.7V to 5.5V and supports frequencies up to 100kHz. The device provides a typical standby pull-up current of 100µA, an active pull-up current of 275µA, and a boost current of 2.2mA during low-to-high transitions. It features 8kV ESD protection on SDA and SCL pins and includes noise filtering with a 20V-ns threshold. The component is housed in a 5-lead SOT-23 package.

Feature Summary

• Active termination for DDC lines enhances system bus signal rise time

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration. Confirm that the procurement channel accepts End-of-Life status components. Ensure the supplier provides traceability documentation for RoHS compliance. Validate the moisture sensitivity level classification prior to soldering operations.

Selection Notes

Select this component when extending DDC bus distances requires faster signal rise times than passive resistors provide. Verify that the application environment falls within the -40°C to +85°C operating temperature range. Ensure the system power supply remains stable between 2.7V and 5.5V. Confirm compatibility with standard I2C-based DDC protocols.
