ISL54103IHZ-T7A

Overview

The ISL54103IHZ-T7A is a dual active pull-up bus terminator designed to accelerate data transmission on DDC 2-wire serial bus 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 boost pull-up current of 2.2mA during low-to-high transitions, reducing signal rise times compared to passive resistors. It features enhanced ESD protection rated at 8kV (HBM) on the SDA and SCL pins. The component is housed in a 5-lead SOT-23 package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Active termination for DDC lines using switched current sources
• Enhanced system bus signal rise time via boosted pull-up current
• Noise filtering prevents activation during invalid input transitions
• Switching behavior invariant across the full operating voltage range

Applications

• Video multiplexers
• Video cable extenders
• Video distribution amplifiers
• Televisions
• Computer monitors

Procurement Notes

Verify that the specific ordering suffix matches the required reel specifications and moisture sensitivity level requirements for the assembly process. Confirm compliance with RoHS directives and Pb-free material sets before finalizing procurement orders.

Selection Notes

Select this component when distributed capacitance from long video cables degrades DDC signal integrity. Ensure the design accommodates the 2.7V to 5.5V supply range and requires active pull-up acceleration rather than simple resistor termination.

Part Context

This part belongs to the ISL54103 series of DDC Accelerators manufactured by Renesas Electronics Corporation. It serves as a specialized interface solution for managing high-capacitance loads on I2C-based Display Data Channel connections in consumer electronics.
