SN74CBTD3384DBR

Overview

The SN74CBTD3384DBR is a digital bus switch IC manufactured by Texas Instruments. It features a 10-bit FET bus switch architecture housed in an SSOP-24 package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. Key electrical parameters include a maximum on-resistance of 20 Ohms and a maximum propagation delay of 150 ps. The component supports surface mount installation and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrates ten independent FET-based bus switches for high-density signal routing
• Provides low on-resistance characteristics to minimize signal attenuation
• Ensures fast switching performance through minimal propagation delay

Applications

• High-speed data bus switching applications
• Portable equipment requiring efficient power management
• Consumer electronics utilizing 5V logic interfaces

Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-24 package configuration when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation prior to integration. Ensure the supply voltage constraints are strictly maintained within the specified operational limits during system design.

Selection Notes

Select this component for designs requiring multiple bidirectional data paths controlled by a single enable signal. The SSOP-24 form factor offers a compact solution for space-constrained printed circuit boards. Evaluate the 20 Ohm on-resistance against the specific load requirements of the target application to ensure signal integrity.

Part Context

This part belongs to the SN74CBTD3384C series of digital bus switches. It serves as a specialized interface solution within Texas Instruments' broader portfolio of logic and switching integrated circuits.
