What are the key features of SN74CBTLV3861PWG4?

  • 10-bit unidirectional bus switch with active-low enable for straightforward signal routing control
  • Ultra-low ON-resistance passes logic signals with near-zero propagation delay and minimal signal distortion
  • 1.65 V to 3.6 V supply range enables mixed-voltage system interfacing between 1.8 V and 3.3 V buses
  • 24-pin TSSOP package with 50 pF load capacitance rating suits high-speed data bus switching applications

What is SN74CBTLV3861PWG4 used for?

The SN74CBTLV3861PWG4 is used in memory bus isolation and data path switching on motherboards, FPGA development boards, and networking line cards where a 10-bit unidirectional switch is needed. Its low-voltage operation between 1.65 V and 3.6 V makes it suitable for interfacing 1.8 V LPDDR memory buses with 3.3 V logic controllers. The device also finds use in test equipment multiplexing and signal path sharing in multi-board embedded systems.

Frequently Asked Questions

Which design use cases are a practical fit for SN74CBTLV3861PWG4?

SN74CBTLV3861PWG4 is a Integrated Circuit from Texas Instruments suited to embedded systems, industrial electronics, communication equipment, test fixtures, and production BOM sourcing. The 24 pins detail helps engineers confirm schematic fit, interface allocation, and sourcing suitability before BOM approval.

How should engineers check package compatibility for SN74CBTLV3861PWG4 during layout review?

Use the Small Outline Packages package information together with 24 pins when comparing footprints, assembly drawings, and mating or socket constraints. This reduces layout risk before prototype or production purchasing.

What should procurement keep aligned when cross-referencing SN74CBTLV3861PWG4 against alternates?

Cross-reference checks should preserve the manufacturer, Integrated Circuit function, package style, lifecycle status, and at least one key parameter such as -40°C to 85°C. Matching these details lowers substitution risk across 1 approved BOM.
