SN74CBT3306PWR

Overview

The SN74CBT3306PWR is a Texas Instruments digital bus switch IC belonging to the 74CBT logic series. It features a 1 x 1:1 configuration with two independent circuits, providing dual outputs in an 8-TSSOP package. The device operates on a single power supply ranging from 4.5V to 5.5V and supports a working temperature range of -40°C to 85°C. Designed for surface mount installation, it functions as a high-speed TTL-compatible FET bus switch.

Feature Summary

• Supports bidirectional data transmission between buses
• Enables partial power-down mode operation to prevent reverse current flow
• Features low on-resistance to minimize signal propagation delay

Applications

• High-speed data switching applications
• Portable equipment requiring low power consumption
• Consumer electronics utilizing 5V logic systems

Procurement Notes

Verify the specific package variant, as this component is identified as 8-TSSOP. Confirm RoHS3 compliance status and check for active manufacturing status or obsolescence notices prior to procurement. Ensure the ordering suffix matches the required tape and reel or cut tape packaging format for your assembly line.

Selection Notes

Select this component when a dual-channel bus switch is required for 5V logic systems. It is suitable for designs needing bidirectional signal routing with minimal insertion loss. Consider the 8-TSSOP footprint constraints and verify that the 4.5V to 5.5V supply voltage aligns with the system architecture.

Part Context

This part belongs to the Texas Instruments 74CBT series of digital bus switches. These devices are designed for high-speed applications where low capacitance and fast switching speeds are critical.
