SN74CB3Q3384APWR

Overview

The SN74CB3Q3384APWR is a 10-bit FET bus switch designed for low-voltage applications, supporting 2.5-V and 3.3-V signaling levels. It features high bandwidth and low on-state resistance (typically 3 Ω). The device operates within a supply voltage range of 2.3 V to 3.6 V and supports data I/Os with 0- to 5-V signaling levels. It is housed in a TSSOP-24 package and functions as a digital bus switch IC.

Feature Summary

• Supports 0- to 5-V signaling levels on data inputs/outputs while operating at lower core voltages
• Provides 10 bits of high-speed TTL-compatible bus switching
• Features low on-state resistance for efficient signal transmission

Applications

• Low-voltage high-bandwidth bus switching
• Portable equipment requiring low power consumption
• Systems interfacing between different voltage domains

Procurement Notes

Verify the RoHS compliance status and specific revision level (Rev. D) against the manufacturer's current datasheet before procurement. Confirm that the TSSOP-24 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when interfacing between 2.5-V or 3.3-V logic systems and 5-V peripherals. It is suitable for applications requiring low insertion loss and high-speed data transfer. Consider the 10-bit width and TSSOP-24 package size relative to board space constraints.

Part Context

This part belongs to the SN74CB3Q series of low-voltage FET bus switches from Texas Instruments. It is distinct from the standard SN74CBT series by its extended input voltage capability and specific low-voltage operation characteristics. It serves as a bridge for mixed-voltage digital systems.

Replacement Considerations

The SN74CBTD3384PWRG4 is a related octal variant but differs in bit count and automotive qualification. Verify pin compatibility and electrical parameters against the SN74CBT3384A family if substituting.
