SN74CB3Q16244DGGR

Overview

The SN74CB3Q16244DGGR is a 16-bit FET bus switch manufactured by Texas Instruments. It operates within a low-voltage range of 2.5 V to 3.3 V and features high-bandwidth performance. The device is housed in a 48-pin TSSOP package with dimensions of 12.5 mm length. It supports bidirectional data flow and utilizes an active-low enable control type. The component complies with RoHS standards, contains no lead, and meets the EAR99 export classification code.

Feature Summary

• Provides 16-bit bidirectional signal switching capability for low-voltage applications
• Utilizes FET technology to achieve high-bandwidth performance
• Operates reliably across a wide industrial temperature range from -40°C to +85°C

Applications

• Low-voltage bus architecture interconnects
• High-speed data line switching
• Portable electronic devices requiring 2.5-V or 3.3-V operation

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component matches the required 48-TSSOP package outline and electrical characteristics for your design. Ensure compliance with RoHS directives and check for any recent product change notifications regarding the manufacturing process or material composition before finalizing procurement.

Selection Notes

Select this component when designing systems that require 16-bit wide bus switching at 2.5-V or 3.3-V logic levels. The high-bandwidth characteristic makes it suitable for applications demanding fast signal transitions. Ensure the PCB layout accommodates the 48-TSSOP footprint and that the operating environment remains within the specified -40°C to +85°C temperature range for optimal reliability.

Part Context

This part belongs to the CB3Q series of low-voltage bus switches from Texas Instruments. These components are designed to replace traditional bipolar bus switches, offering lower on-resistance and improved power efficiency. The DGGR suffix indicates a specific reel-based packaging format intended for automated surface-mount assembly processes in high-volume manufacturing environments.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters carefully when considering equivalent parts from other manufacturers.
