SN74CBT16211DL

Overview

The SN74CBT16211DL is a 24-bit FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4.5V to 5.5V and features two independent circuits, each configured as 12 x 1:1 switches. The device is housed in a 56-BSSOP package with a width of 0.295 inches (7.50mm). It supports surface mount installation and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Functions as a low-resistance digital bus switch for signal routing
• Provides electrical isolation between input and output lines when disabled
• Supports bidirectional data transmission across the bus lines

Applications

• High-speed data bus switching in computer systems
• Signal routing in telecommunications equipment
• Consumer electronics requiring multiple bus configurations

Procurement Notes

Verify the specific suffix 'DL' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure the component meets RoHS3 compliance requirements if mandated by the target assembly process. Cross-reference the 56-BSSOP footprint with PCB design libraries to prevent mounting errors during production integration.

Selection Notes

Select this component when a 5.5V logic interface requires high-density bus switching capabilities. The 56-pin BSSOP package offers a compact solution for space-constrained designs. Consider the 4.5V minimum supply voltage constraint when designing power rails for the system environment.

Part Context

This part belongs to the Texas Instruments 74CBT series of bus switches. It serves as a functional alternative to other 24-bit switches in the family, such as the SN74CBT16211DGGR, though package variations exist. The series is designed for applications demanding low on-resistance and minimal signal distortion.

Replacement Considerations

SN74CBT16211CDGGR is listed as a manufacturer-recommended substitute.
