SN74CBT3244CPWR

Overview

The SN74CBT3244CPWR is an octal FET bus switch manufactured by Texas Instruments. It operates within a voltage range of 1.65 V to 3.6 V and supports bidirectional data transmission across eight independent channels. The device features low on-resistance and low leakage current, ensuring signal integrity in high-speed applications. It is housed in a 20-pin TSSOP package with a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent bidirectional bus switching channels
• Low on-resistance for minimal signal attenuation during conduction
• Low leakage current to maintain power efficiency when inactive
• Compatible with standard logic families including TTL and CMOS

Applications

• Portable equipment requiring low-voltage operation
• Consumer electronics utilizing high-density bus architectures
• Computing systems needing efficient signal routing between components
• Industrial control modules with strict power constraints

Procurement Notes

Verify the specific suffix CPWR corresponds to the 20-TSSOP package and reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the manufacturer part number matches the exact ordering code to avoid pinout or electrical characteristic mismatches during integration.

Selection Notes

Select this component when designing circuits that require multiple bidirectional switches in a compact form factor. The low voltage capability makes it suitable for modern low-power systems. Consider the package size and thermal characteristics relative to the PCB layout. Evaluate the propagation delay and on-resistance against the system's bandwidth requirements.

Part Context

This part belongs to the SN74CBT series of bus switches, designed for high-speed data transfer in space-constrained environments. The CBT family utilizes advanced technology to achieve low resistance and fast switching speeds. It serves as a critical interface component for managing data flow in complex digital systems.

Replacement Considerations

Check for direct equivalents such as the SN74CBT3244CDWR or SN74CBT3244RGYR if different packaging options are required. Verify functional compatibility with other octal bus switches from the same manufacturer before substitution.
