Overview
The SN74CBT16214DGGR is a high-speed TTL-compatible FET multiplexer/demultiplexer manufactured by Texas Instruments. It provides 12 bits of bus switching between three separate ports, functioning as a 12-bit 1-of-3 switch. The device operates within a supply voltage range of 4 V to 5.5 V and supports surface mount installation in a 56-TSSOP package. It is designed for low ON-state resistance applications and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides 12-bit high-speed bus switching capability between three distinct ports
- Features low ON-state resistance for efficient signal transmission
- Maintains TTL compatibility for seamless integration with standard logic families
Applications
- High-speed data routing in digital systems
- Bus switching interfaces requiring multiple port selection
- Signal multiplexing in consumer electronics
Procurement Notes
Verify the specific ordering suffix DGGR confirms the TSSOP-56 package and reel packaging configuration. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the manufacturer part number with official Texas Instruments documentation to confirm current production status and availability before finalizing procurement plans.
Selection Notes
Select this component when a 12-bit wide bus requires switching among three distinct destinations or sources. The 1-of-3 architecture distinguishes it from standard 1-of-2 switches. Verify that the 4V to 5.5V supply voltage range aligns with the system power rails and that the TSSOP-56 footprint fits the PCB layout constraints.
Part Context
This device belongs to the Texas Instruments SN74CBT series, which focuses on high-speed CMOS bus switches. The SN74CBT16214 variant specifically addresses multi-port switching needs, differing from the SN74CBT16211 which typically offers 1-of-1 configurations. It serves as a specialized solution for complex bus matrix routing compared to simpler single-path switches.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Texas Instruments documentation for potential pin-compatible alternatives or updated revisions.
