SN74CBTD3384DW

Overview

The SN74CBTD3384DW is a digital bus switch integrated circuit manufactured by Texas Instruments. It features ten independent FET bus switches arranged in two groups of five, each controlled by a dedicated control pin. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 24-pin SSOP package. Key electrical specifications include a maximum on-resistance of 20 Ohms and a maximum propagation delay of 150 ps. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides ten independent single-pole single-throw (SPST) bus switches for signal routing
• Features low on-resistance for efficient signal transmission
• Supports bidirectional data flow with separate control pins for each group

Applications

• High-speed data bus switching applications
• Portable equipment requiring low power consumption
• Consumer electronics utilizing 5V logic systems

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target system's voltage levels and thermal requirements before procurement. Cross-reference the full part number with authorized distributors to confirm current availability status and authenticity.

Selection Notes

Select this component when designing circuits that require multiple isolated signal paths controlled independently. The dual-control architecture allows flexible configuration of data buses. Consider the SSOP package dimensions for PCB layout constraints and verify that the 5V supply rail aligns with the system's power distribution network.

Part Context

This device belongs to the SN74CBTD3384C series of high-speed bus switches. It is designed to replace mechanical relays or other switching mechanisms in modern electronic designs. The series offers improved performance characteristics compared to older logic families, focusing on speed and power efficiency for portable and consumer applications.

Replacement Considerations

Check for equivalent parts such as the SN74CBTD3384CDWR or SN74CBTD3384PWRG4 if different packaging options are required. Verify pinout compatibility and electrical parameters before substituting.
