SN74CBTLV3245ARGYR

Overview

The SN74CBTLV3245ARGYR is an octal FET bus switch manufactured by Texas Instruments, designed for low-voltage digital applications. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data transmission across eight channels. The device features a maximum on-resistance of 7 Ohms and a propagation delay of 250 ps, ensuring efficient signal integrity in high-speed environments. It is housed in a 20-pin MicroStar Junior BGA package (4x3 mm) suitable for surface-mount installation. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal FET architecture providing eight independent bidirectional switching channels
• Low on-resistance characteristic supporting minimal signal attenuation
• Direction control pin enabling precise management of data flow direction
• Compatible with low-voltage power supplies for energy-efficient operation

Applications

• Portable consumer electronics requiring compact bus switching solutions
• Mobile communication devices utilizing low-voltage logic interfaces
• Industrial control systems operating within specified temperature ranges
• High-density printed circuit board designs necessitating small form factors

Procurement Notes

Verify the specific suffix 'ARGYR' against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 20-pin MicroStar Junior configuration. Confirm that the operating voltage requirements align with the target system's power rails before integration.

Selection Notes

Select this component when designing circuits that require multiple bidirectional switches in a constrained physical space. The low on-resistance makes it suitable for maintaining signal quality in high-frequency applications. Consider the thermal performance and package size relative to other available options in the SN74CBTLV3245A family to ensure optimal system integration.

Part Context

This part belongs to the SN74CBTLV3245A series of octal bus switches from Texas Instruments. The series is characterized by its ability to handle low-voltage signals with high efficiency. The specific variant utilizes a MicroStar Junior BGA package, distinguishing it from SOIC or SSOP versions within the same functional family. This packaging allows for higher pin density and improved thermal dissipation compared to traditional leaded packages.

Replacement Considerations

The SN74CBTLV3245AZQNR is a documented substitute within the same product family. Verify pinout compatibility and package dimensions before substitution. Ensure that any alternative component meets the same electrical specifications and environmental ratings required by the design.
