SN74CB3Q16244DGVR

Overview

The SN74CB3Q16244DGVR 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 suitable for data-intensive applications. The device is housed in a 48-pin TSSOP package with a width of 0.3 inches. It supports bidirectional data flow and utilizes an active-low enable control type. The component is designed for surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit bidirectional data switching capability using FET technology
• Optimized for low-voltage operation at 2.5 V and 3.3 V supply levels
• Features high-bandwidth performance for efficient signal transmission
• Utilizes an active-low enable control mechanism for circuit management

Applications

• Portable equipment requiring low-power signal routing
• Consumer electronics utilizing high-speed data buses
• Computing systems needing compact bus switching solutions

Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the tape-and-reel packaging configuration when sourcing. Confirm that the 48-TSSOP footprint matches the target PCB layout dimensions. Ensure the operating voltage requirements align with the 2.5-V to 3.3-V specification range. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a 16-bit wide bus interface is required within a constrained physical space. The choice is appropriate for designs prioritizing low voltage operation over higher voltage tolerance. Consider the TSSOP package constraints regarding pin pitch and board real estate. Evaluate the need for bidirectional switching capabilities inherent to this bus switch architecture.

Part Context

This part belongs to the SN74CB3Q series, which focuses on automotive-grade or high-reliability low-voltage logic devices. The CB3Q designation indicates specific qualification standards distinct from standard commercial logic families. It serves as a bridge between general-purpose logic and specialized high-performance switching needs in modern electronic systems.

Replacement Considerations

The SN74CB3Q16244DGGR is a verified substitute offering identical electrical characteristics but packaged in a tube instead of a reel. Verify that the change in packaging format does not impact automated assembly processes.
