SN74CB3T16211DL

Overview

The SN74CB3T16211DL is a 24-bit FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V, supporting both 2.5-V and 3.3-V low-voltage systems. The device features an on-resistance of 9.5 ohms maximum and a propagation delay of 250 ps maximum. It is housed in a 56-pin TSSOP package and functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-bandwidth signal switching for 24-bit data paths
• Supports low-voltage operation at 2.5 V and 3.3 V
• Ensures signal integrity with low on-resistance characteristics

Applications

• High-speed digital bus switching applications
• Portable equipment requiring low-power signal routing
• Consumer electronics utilizing 2.5-V or 3.3-V logic levels

Procurement Notes

Verify the specific suffix 'DL' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before integration into the design.

Selection Notes

Select this component when designing circuits that require switching 24-bit wide buses at low voltages. Consider the 56-pin TSSOP footprint constraints and the 2.3 V to 3.6 V supply requirements during schematic capture and layout planning.

Part Context

This part belongs to the SN74CB3T1621x series of low-voltage FET bus switches. These devices are designed for high-speed data transmission in portable and consumer electronic applications where power efficiency and signal fidelity are critical.

Replacement Considerations

SN74CB3T16211DGGR shares identical electrical specifications but utilizes a TSSOP-56 reel package instead of the tube-packaged DL variant.
