SN74CBT3244PWR

Overview

The SN74CBT3244PWR is an octal FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4V to 5.5V and supports bidirectional data transmission. The device features TTL-compatible control inputs and low on-resistance for efficient signal routing. It is housed in a 20-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent bidirectional switching channels
• Low on-resistance design ensures minimal signal attenuation across the bus
• TTL-compatible control inputs simplify interface with standard logic families

Applications

• Portable equipment requiring low-voltage operation
• Consumer electronics utilizing high-density bus architectures
• Computing systems needing efficient signal routing between components

Procurement Notes

Verify the specific suffix PWR indicates the 20-pin TSSOP package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the voltage range aligns with the system's 4V to 5.5V supply constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring multiple bidirectional switches in a compact surface-mount package. Compare against similar devices like the SN74CBT3245 if unidirectional buffering is sufficient, as pinouts may differ. Verify that the 20-pin TSSOP footprint matches the PCB layout constraints and thermal requirements of the design.

Part Context

This part belongs to the Texas Instruments 74CBT series of bus switches. These devices are designed for low-voltage digital applications where space and power efficiency are critical. The series offers various configurations including quad and octal options to suit different channel density needs in modern electronic systems.

Replacement Considerations

SN74CBT3244PW: Same function in a 20-pin TSSOP tube package instead of tape-and-reel.
