SN74CB3Q16210DGVR

Overview

The SN74CB3Q16210DGVR is a 20-bit FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V, supporting 2.5-V and 3.3-V low-voltage applications. The device features a maximum on-resistance of 9.5 Ohms and a maximum propagation delay of 250 ps. It is housed in a 48-pin TVSSOP package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides high-bandwidth signal switching for 20 independent data lines
• Supports low-voltage operation at 2.5 V and 3.3 V
• Ensures signal integrity through low on-resistance characteristics

Applications

• High-speed data bus switching in consumer electronics
• Signal routing in portable computing devices
• Memory expansion systems requiring low-latency switching

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSSOP-48 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and lead times directly with Texas Instruments or authorized distributors, as manufacturing parameters may vary by production batch. Ensure the component meets the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when designing circuits that require switching twenty parallel signals simultaneously. It is suitable for applications demanding low power consumption and fast switching speeds within the 2.3 V to 3.6 V supply range. Consider the TVSSOP-48 package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the SN74CB3Q16210 family of 20-bit FET bus switches from Texas Instruments. The 'Q' designation typically indicates automotive qualification standards, while 'DGVR' specifies the TVSSOP-48 package and reel packaging. This series is designed for high-performance data transfer applications requiring reliable signal isolation and routing.

Replacement Considerations

The SN74CB3Q16210DL is a documented alternative offering identical functional specifications but utilizing a 48-pin SSOP package instead of TVSSOP. Verify pin compatibility and thermal performance differences before substitution.
