74CBTLV3244QG8

Signal Switches, Multiplexers, Decoders Overview

The Renesas Electronics Corporation 74CBTLV3244QG8 is an octal bus switch IC belonging to the 74CBTLV series. It features a 4 x 1:1 circuit configuration with two independent control sections, each managing four bidirectional switches. The device operates on a single power supply ranging from 2.3V to 3.6V and supports data transmission at -40°C to +85°C. It is housed in a 20-lead QSOP package with a width of 3.90mm.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides standard '244 logic pinout compatibility for direct replacement in existing designs.
• Features 5Ω on-resistance for efficient A/B bidirectional signal switching.
• Maintains high isolation between ports when the output enable signal is inactive.
• Ensures protection against overvoltage conditions during power-off states.

Signal Switches, Multiplexers, Decoders Applications

• Asynchronous communication interfaces between data buses
• Low-voltage system bus architecture routing
• Mixed 5V/3.3V voltage level translation circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS3 compliance status and check for specific Product Change Notices regarding assembly site updates or label changes prior to finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring low-voltage operation within the 2.3V to 3.6V range. Ensure the design accommodates the 20-QSOP package dimensions and surface mount installation requirements while maintaining thermal performance within the specified industrial temperature limits.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74CBTLV family of low-voltage bus switches manufactured by Renesas Electronics. It serves as a successor to legacy IDT products, offering enhanced performance characteristics such as lower on-resistance and improved latch-up protection compared to standard logic families.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74CBTLV3244PGG8 is a parameter-equivalent alternative available in TSSOP packaging. Verify pinout compatibility and package dimensional differences before substituting the obsolete QSOP variant in active designs.
