SN74CB3Q3384APW

Overview

The SN74CB3Q3384APW is a 10-bit FET bus switch designed for 2.5-V and 3.3-V low-voltage applications with high bandwidth capabilities. It operates within a supply voltage range of 2.3 V to 3.6 V and supports data I/Os compatible with 0- to 5-V signaling levels. The device features an on-resistance (ron) of 3 Ω typical and maintains an operating temperature range from -40°C to +85°C. Packaged in a 24-TSSOP format, it serves as a general-purpose solution for signal routing in mixed-voltage systems.

Feature Summary

• Supports 0- to 5-V signaling levels on data I/Os despite lower core supply voltages
• Provides high-bandwidth performance suitable for fast signal switching applications
• Features low on-resistance characteristics for efficient signal transmission

Applications

• General-purpose FET bus switching in mixed-voltage environments
• Signal routing between 2.5-V and 3.3-V logic domains
• High-speed data line buffering and isolation

Procurement Notes

Verify the specific suffix 'APW' against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the component meets RoHS compliance standards if required by your assembly process. Cross-reference the package type TSSOP-24 dimensions with your PCB footprint library to guarantee mechanical compatibility during procurement and placement.

Selection Notes

Select this component when interfacing between different voltage domains requiring 5-V tolerance on input/output pins while maintaining low power consumption. It is appropriate for designs needing high bandwidth and low on-resistance without complex control logic. Consider the 24-TSSOP package constraints and thermal dissipation capabilities relative to your board layout and ambient operating conditions.

Part Context

This part belongs to Texas Instruments' SN74CB3Q series of low-voltage FET bus switches. It is functionally related to other devices in the CB3Q family, such as the SN74CB3Q3251 multiplexer, but offers distinct 10-channel parallel switching capabilities. The series is characterized by its ability to handle wide voltage swings on I/O lines while operating on lower internal supply rails.

Replacement Considerations

Check for direct equivalents like the SN74CB3T3383PW or SN74CB3Q3384A variants, ensuring pin compatibility and electrical parameter alignment. Verify that any substitute maintains the same 5-V tolerant I/O capability and package outline to avoid redesigning the PCB layout.
