SN74CBT16211CDL

Overview

The SN74CBT16211CDL is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments. It operates as a dual 12-bit bus switch or a single 24-bit bus switch, providing low ON-state resistance (ron). The device features –2-V undershoot protection and functions with a supply voltage range of 4.5V to 5.5V. It is housed in a 56-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• High-speed TTL-compatible FET bus switch architecture
• Configurable as dual 12-bit or single 24-bit switch
• Integrated –2-V undershoot protection
• Low ON-state resistance for efficient signal transmission

Applications

• High-speed data bus switching applications
• Portable systems requiring low power consumption
• Consumer electronics with TTL-compatible interfaces
• Industrial control systems operating within specified temperature ranges

Procurement Notes

Verify the specific suffix 'DL' indicates the 56-pin SSOP package configuration when sourcing. Confirm that the component meets the required operating temperature range of -40°C to +85°C for your specific environment. Ensure compatibility with the 4.5V to 5.5V supply voltage range. Check for RoHS compliance status if environmental regulations apply to your assembly process. Validate pinout alignment with your PCB layout design before finalizing procurement.

Selection Notes

Select this component when a high-density bus switch solution is required in a compact surface-mount package. The dual 12-bit configuration offers flexibility for separate bus management. Consider the –2-V undershoot protection feature for robust operation in noisy environments. Ensure the system logic levels are compatible with the TTL-compatible input requirements. Verify that the 56-pin SSOP footprint fits within the available board space constraints.
