SN74CBT16214CDL

Overview

The SN74CBT16214CDL is a 12-bit 1-of-3 FET multiplexer/demultiplexer manufactured by Texas Instruments. It belongs to the 74CBT logic series and operates within a supply voltage range of 2.5 V to 3.6 V. The device features a TSSOP-48 package suitable for surface-mount applications. It supports an operating temperature range from -40°C to +85°C. This component functions as a high-speed data selector, enabling signal routing between multiple inputs and a single output or vice versa.

Feature Summary

• Provides 12-bit parallel data switching capability with three selectable input channels.
• Utilizes FET technology for low on-resistance and minimal signal distortion.
• Designed for low-voltage digital systems requiring efficient bus management.

Applications

• Data routing in portable electronic devices
• Signal selection in consumer electronics
• Bus exchange configurations in communication equipment

Procurement Notes

Verify the specific suffix 'CDL' against the manufacturer's current datasheet to confirm package type and electrical characteristics. Ensure compatibility with the target system's voltage levels and thermal requirements. Cross-reference the part number with official Texas Instruments documentation to validate availability and revision status before procurement.

Selection Notes

Select this component when a 12-bit wide multiplexing function is required within a limited pin count constraint. The 1-of-3 configuration offers flexibility for selecting among three distinct data sources. Consider the TSSOP-48 package dimensions for PCB layout planning. Verify that the 2.5 V to 3.6 V operating range aligns with the system power supply architecture.

Part Context

This part is part of the Texas Instruments 74CBT family, which focuses on low-voltage, high-speed CMOS logic. The CBTLV sub-series typically targets lower voltage applications, while standard CBT parts may support wider ranges. The SN74CBT16214 specifically addresses the need for wide-bus switching in compact form factors common in modern mobile and handheld devices.

Replacement Considerations

Consult the Texas Instruments product selection guide for direct replacements within the 74CBT1621x series. Verify pinout compatibility and electrical specifications such as propagation delay and on-resistance. Alternative manufacturers may offer similar 12-bit multiplexers, but functional equivalence must be confirmed through detailed datasheet comparison.
