Overview
The SN74CBTLV3857DWG4 is a digital bus switch IC from the Texas Instruments SN74CBTLV3857 series. It features a 10-bit FET configuration with pull-down resistors. The device operates within a supply voltage range of 3 V to 3.6 V, typically at 3.3 V. Key electrical parameters include a maximum on-resistance of 8 Ohms and a maximum propagation delay of 250 ps. It supports surface mount installation in an SOIC-24 package and functions across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates ten independent field-effect transistor (FET) switches for high-density data routing
- Includes internal pull-down resistors to define default logic states
- Provides bidirectional signal transmission capability between buses
Applications
- High-speed data bus switching in consumer electronics
- Signal routing in portable computing devices
- Interface isolation in industrial control systems
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's current product status documentation to confirm active manufacturing or lifecycle stage. Ensure the SOIC-24 package outline matches the target PCB footprint requirements. Cross-reference the RoHS compliance details with the latest official datasheet revision to meet environmental regulations.
Selection Notes
Select this component when a 10-bit wide bus interface is required within a low-voltage 3.3 V system architecture. The choice is driven by the need for low on-resistance and fast switching speeds in compact surface-mount designs. Evaluate the thermal performance and pin count constraints relative to alternative packages before finalizing the design.
Part Context
This part belongs to the SN74CBTLV3857 family of low-voltage bus switches. It serves as a variant of the standard SN74CBTLV3857DWR, distinguished by its lead-free construction and specific packaging designation. The family is designed for applications requiring efficient signal management in space-constrained electronic assemblies.
Replacement Considerations
The SN74CBTLV3857DWR is a confirmed functional substitute within the same series. Verify that the replacement maintains identical pinout compatibility and electrical specifications for the specific application environment.
