SN74CBTLV3383DWE4

Overview

The SN74CBTLV3383DWE4 is a low-voltage 10-bit FET bus-exchange switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. The device features a maximum on-resistance of 27 Ohms and a maximum propagation delay of 250 ps. It is housed in a SOIC-24 surface-mount package.

Feature Summary

• Provides ten bits of high-speed bus switching or exchanging capabilities
• Enables rail-to-rail switching on data I/O ports for full signal integrity
• Supports partial-power-down mode operation through Ioff functionality

Applications

• High-speed digital bus switching applications
• Bus exchange configurations requiring low latency
• Systems utilizing partial-power-down modes

Procurement Notes

Verify the specific suffix 'E4' against current manufacturer documentation to confirm environmental compliance status, as this designation may indicate lead-free or RoHS-compliant variations distinct from standard versions. Ensure the SOIC-24 package footprint matches the design requirements. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require simultaneous switching of ten independent data lines with minimal signal distortion. The low on-resistance makes it suitable for maintaining signal quality across long traces. Verify that the system power supply remains strictly within the 2.3 V to 3.6 V operational window to ensure correct functionality and prevent device damage.

Part Context

This part belongs to the SN74CBTLV3383 series of low-voltage bus switches. It is functionally equivalent to the SN74CBTLV3383DW but includes the 'E4' suffix, which typically denotes specific manufacturing or environmental compliance attributes defined by Texas Instruments. It serves as a high-performance alternative to standard logic buffers in complex digital systems.

Replacement Considerations

The SN74CBTLV3383DW is a direct functional substitute within the same family. Verify pinout compatibility and package dimensions (SOIC-24) before substitution. Confirm that any differences in environmental certifications or manufacturing lot codes do not impact the specific application requirements.
