TPT29548A-TS5R

Specialized Overview

The TPT29548A-TS5R is an 8-channel bidirectional translating I2C switch in a TSSOP24 package. It operates with a supply voltage of 2.3 V to 5.5 V and supports Standard Mode (100 kHz) and Fast Mode (400 kHz). The device features an active-low reset input, three hardware address pins for up to eight devices on the bus, and low RON switches. It allows voltage-level translation between 2.5-V, 3.3-V, and 5-V buses without additional protection. All I/O terminals are 5.5 V tolerant, and it provides ESD protection exceeding 3.5-kV HBM and 1.5-kV CDM.

Specialized Feature Summary

• Bidirectional translation across multiple downstream channels
• Active-low reset input for system recovery
• Supports hot insertion and latch-up performance

Specialized Applications

• Servers and storage systems
• Telecom switching equipment routers
• Factory automation systems
• Resolving I2C slave address conflicts

Specialized Procurement Notes

Verify the TPT29548A-TS5R datasheet revision B.2 for confirmed hot insertion support. Confirm the TSSOP24 package marking '9548A' and tape reel quantity of 4000 units. Ensure compliance with RoHS and halogen-free requirements as defined by the manufacturer.

Specialized Selection Notes

Select this component when expanding a single I2C master interface to multiple slaves with identical addresses. Verify that the required clock frequency does not exceed 400 kHz. Ensure the system voltage levels fall within the supported 2.3 V to 5.5 V range for proper level translation.

Specialized Part Context

This part belongs to the TPT29548A family of I2C switches. The TS5R suffix specifically denotes the TSSOP24 package variant with a 4000-unit tape and reel quantity. It shares functional specifications with the QFN24 version but differs in physical footprint and thermal characteristics.
