SN74CBTS3384PW

Overview

The SN74CBTS3384PW is a 10-bit FET bus switch with Schottky diode clamping, organized as two independent 5-bit switches. It operates within a supply voltage range of 4 V to 5.5 V and supports an operating temperature from -40°C to 85°C. The device features TTL-compatible input levels and low on-state resistance (typically 5 Ω at 4.5 V). Propagation delay is typically 0.25 ns at 5 V. Control inputs require a high-level voltage of at least 2 V and a low-level voltage of no more than 0.8 V.

Feature Summary

• Integrates ten bits of high-speed bus switching functionality divided into two separate 5-bit channels.
• Incorporates Schottky diodes on the I/O pins to clamp undershoot voltages for signal integrity.
• Provides TTL-compatible input levels to ensure seamless interface with standard logic families.
• Features low on-state resistance to minimize propagation delay during active switching operations.

Applications

• High-speed data bus routing in digital systems
• Signal path selection between multiple ports
• Interface bridging between different logic voltage domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package options. Confirm that the PW tube variant matches the required quantity per tube, while the PWR tape-and-reel option suits automated assembly needs. Ensure the selected part status aligns with long-term production requirements.

Selection Notes

Select this component when a 10-bit bus switch with Schottky protection is required. Verify that the control input thresholds meet the system's logic level specifications. Ensure the operating temperature range covers the intended environmental conditions. Check if the TSSOP-24 package dimensions fit the available PCB footprint.

Part Context

This device belongs to the SN74CBTS3384 family of 10-bit FET bus switches. The PW designation indicates a TSSOP-24 tube package. Other variants include DWR, DBR, and DGVR packages. The family provides high-speed switching capabilities with integrated protection features suitable for demanding digital applications.

Replacement Considerations

Check the manufacturer's official replacement list for direct substitutes. Verify pin compatibility and electrical characteristics before swapping. Consider package differences such as TSSOP versus SSOP or SOIC when selecting alternatives.
