SN74CBT16214DL

Overview

The SN74CBT16214DL is a 12-bit, 1-of-3 FET multiplexer/demultiplexer from Texas Instruments' 74CBT logic series. It operates on a single power supply ranging from 1.65V to 3.6V and supports data rates up to 1.2Gbps. The device features low on-resistance (typically 8 ohms) and extremely low off-leakage current (less than 10nA). It includes an active-low output enable pin and offers high input protection exceeding 1.3V above VCC. Packaged in a 64-pin TSSOP with a 0.65mm pitch, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports simultaneous bidirectional data transmission across twelve independent channels
• Provides flexible routing through three selectable inputs per channel for signal selection
• Maintains low signal distortion via minimal on-resistance and flat bandwidth characteristics
• Ensures system reliability with robust electrostatic discharge protection capabilities

Applications

• High-speed data bus switching in portable electronic devices
• Signal routing in telecommunications infrastructure equipment
• Multiplexing control lines in industrial automation systems
• Data path selection in consumer multimedia hardware

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 that the voltage levels and signal integrity requirements of your application align with the component's operational limits. Cross-reference the datasheet for any recent lifecycle status updates or recommended design changes before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring high-density signal routing with low insertion loss. It is suitable for applications demanding fast switching speeds and precise signal integrity over long traces. Consider the 64-pin TSSOP package constraints regarding board space and thermal management. Evaluate the need for multiple input sources per channel to determine if the 1-of-3 configuration meets the system architecture requirements.

Part Context

This part belongs to the Texas Instruments 74CBT family, which focuses on low-voltage, high-speed bus switches. These components are engineered to replace older logic families in modern low-power designs. The 16214 variant specifically addresses the need for complex signal routing in compact form factors common in contemporary digital electronics.

Replacement Considerations

Consult the manufacturer's official substitution guide for verified alternatives. Check for equivalent parts with compatible pinouts and electrical characteristics if sourcing issues arise.
