Overview
The SN74CBTLV3861PW 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 a maximum on-state resistance of 40 Ohms and a maximum propagation delay of 250 ps. It utilizes a TSSOP-24 package with a flow-through architecture. The component includes an Ioff feature for partial-power-down mode support and latch-up performance exceeding 100 mA per JESD 78, Class II.
Feature Summary
- Provides ten bits of high-speed bus switching with rail-to-rail switching capability on data I/O ports.
- Supports partial-power-down applications through the Ioff feature, ensuring isolation during power off.
- Features a flow-through architecture designed to optimize printed circuit board layout.
Applications
- Partial-power-down mode operations
- High-speed bus switching
- Rail-to-rail signal routing
Procurement Notes
Verify that the specific part number matches the required TSSOP-24 package configuration. Confirm the operating temperature range aligns with system requirements, specifically the -40°C to +85°C specification. Ensure the supply voltage constraints between 2.3 V and 3.6 V are compatible with the target application design parameters.
Selection Notes
Select this component when a low-voltage 10-bit bus switch is required for high-speed signal routing. The device is suitable for applications needing rail-to-rail switching and minimal propagation delay. Consider the flow-through architecture if printed circuit board layout optimization is a priority for the design.
Part Context

FAQ
How does the device handle partial-power-down scenarios?
The device supports partial-power-down applications using the Ioff feature, which ensures that damaging current will not backflow through the device when it is powered down.
What is the function of the OE pin?
When the output enable (OE) pin is low, the 10-bit bus switch is on, connecting port A to port B. When OE is high, the switch is open, creating a high-impedance state between the two ports.
