74CBTD3384CDGVRG4

Signal Switches, Multiplexers, Decoders Overview

The SN74CBTD3384CDGVRG4 is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments. It features low ON-state resistance and bidirectional data flow with near-zero propagation delay. The device includes an integrated diode to VCC for level shifting from 5-V inputs down to 3.3-V outputs. It supports partial-power-down applications via Ioff, ensuring no backflow current when powered down. Undershoot protection on A and B ports handles signals up to -2 V. Operating voltage ranges from 4.5 V to 5.5 V, supporting 0 to 5-V signaling levels.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrated diode to VCC provides level shifting for 5-V input down to 3.3-V output levels
• Active undershoot-protection circuitry ensures proper OFF state during undershoot events up to -2 V
• Ioff feature supports partial-power-down mode operation without damaging backflow current
• Bidirectional data flow with low ON-state resistance minimizes propagation delay

Signal Switches, Multiplexers, Decoders Applications

• Memory interleaving
• Bus isolation
• Low-distortion signal gating

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the package type matches the design requirements, as this specific part number corresponds to the TVSOP-24 (DGV) configuration. Confirm RoHS compliance and lead finish specifications against the latest TI Package Option Addendum. Ensure ordering suffixes align with tape-and-reel quantities if applicable. Cross-reference the active status in official catalogs before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring high-speed switching with minimal signal distortion. The integrated level-shifting capability simplifies interfacing between 5-V and 3.3-V domains. Consider the TVSOP-24 package constraints for PCB layout. Verify control input compatibility with available driver logic levels to ensure reliable OE pin operation across the full temperature range.
