SN74CBTLV3861DW

Overview

The SN74CBTLV3861DW is a low-voltage 10-bit FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an operating temperature range from -40°C to 85°C. The device features rail-to-rail switching on data I/O ports and includes an Ioff function that supports partial-power-down mode operation. It utilizes a flow-through architecture to optimize PCB layout and provides latch-up performance exceeding 100 mA per JESD 78, Class II standards.

Feature Summary

• Provides ten bits of high-speed bus switching with low on-state resistance for minimal propagation delay
• Supports partial-power-down applications through the Ioff feature to prevent damaging backflow current when powered down
• Features a flow-through architecture designed to optimize printed circuit board layout

Applications

• Partial-power-down mode operations requiring isolation during power off
• High-speed bus switching connections between two ports
• Rail-to-rail switching on data input/output ports

Procurement Notes

Verify the specific package type and ordering suffix against the manufacturer's official documentation before procurement. Confirm that the component meets the required RoHS compliance and material specifications for your application. Ensure that all unused control inputs are properly tied to VCC or GND to guarantee correct device operation as specified in the recommended operating conditions.

Selection Notes

Select this component for designs requiring low-voltage operation between 2.3 V and 3.6 V. The device is suitable for applications needing rail-to-rail switching capabilities and protection against backflow current during power-down states. Consider the SOIC-24 package dimensions and thermal impedance characteristics when designing the printed circuit board layout for adequate heat dissipation.

FAQ

How does the Ioff feature benefit the device?

The Ioff feature ensures that damaging current will not backflow through the device when it is powered down, providing necessary isolation during partial-power-down applications.

What is the recommended handling for unused control inputs?

All unused control inputs must be held at VCC or GND to ensure proper device operation and prevent undefined states.
