SN74CBT3245CPWR

Overview

The SN74CBT3245CPWR is an octal FET bus switch manufactured by Texas Instruments. It features a single 8-bit bidirectional data path with one control signal. The device operates within a supply voltage range of 4V to 5.5V and supports a maximum working power supply voltage of 5V. Key electrical parameters include a maximum on-resistance of 12 ohms and a maximum propagation delay of 150 ps. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a 20-TSSOP package with a width of 4.40mm.

Feature Summary

Provides bidirectional data transmission through a single octet configuration controlled by one enable signal.
Utilizes FET technology to achieve low on-resistance for efficient signal integrity.
Designed for surface-mount installation in compact electronic assemblies.

Applications

Portable equipment requiring high-speed data switching
Consumer electronics utilizing 5V logic interfaces
Computing products needing bidirectional bus translation

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging format when sourcing. Confirm that the intended application voltage aligns with the 4V to 5.5V operational range. Ensure thermal management meets the -40°C to +85°C industrial temperature specifications. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when an octal bidirectional switch is required for 5V systems. The 12-ohm on-resistance suits applications prioritizing moderate drive capability over ultra-low resistance alternatives. The 150 ps delay offers sufficient speed for general-purpose digital buses. Consider the 20-TSSOP footprint for PCB layout compatibility.

Part Context

This device belongs to the SN74CBT3245C series of digital bus switches. It serves as a solution for managing multiple data lines simultaneously in 5V logic environments. The series is designed to replace mechanical relays or discrete transistor arrays in modern surface-mount designs.

Replacement Considerations

SN74CBT3245CPW is a tube-packaged variant of the same functional device. SN74CBT3245CDBR shares identical electrical characteristics but utilizes an SSOP-20 package. Verify pinout and physical dimensions before substituting packages.
