74CBTD3384CDGVRE4

Signal Switches, Multiplexers, Decoders Overview

The SN74CBTD3384CDGVR is a high-speed TTL-compatible FET bus switch housed in a 24-pin TVSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data I/O levels from 0 V to 5 V. The device features an internal diode for level shifting, allowing 5-V inputs to interface with 3.3-V outputs. It includes active undershoot protection on A and B ports up to -2 V. Electrical characteristics include a typical ON-state resistance of 3 Ω and a maximum propagation delay of 0.15 ns at 5 V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrated series diode enables level shifting from 5-V input down to 3.3-V output
• Active undershoot-protection circuitry safeguards against negative voltage events up to -2 V
• Supports partial-power-down mode via Ioff feature to prevent backflow current
• Bidirectional data flow with near-zero propagation delay

Signal Switches, Multiplexers, Decoders Applications

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

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the ordering suffix 'E4' corresponds to lead-free (NIPDAU) finish and RoHS compliance as listed in the Package Option Addendum. Confirm the DGV package designation matches the required TVSOP-24 footprint. Ensure the operating temperature range of -40°C to 85°C aligns with system requirements.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing between 5-V and 3.3-V domains requiring bidirectional switching. The integrated level-shifting diode simplifies design by eliminating external components. Verify that the control inputs are compatible with TTL or 5-V/3.3-V CMOS logic levels for proper enable/disable operation.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74CBTD3384C family of high-speed FET bus switches. It is functionally equivalent to other variants such as SN74CBTD3384CDWR (SOIC) or SN74CBTD3384CPWR (TSSOP), differing primarily in the physical package type while maintaining identical electrical specifications and pinout configurations.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SN74CBTD3384CDGVRG4 is a confirmed substitute with identical specifications and NIPDAU finish.
