SN74CBTLV3245APW

Overview

The SN74CBTLV3245APW is an octal FET bus switch manufactured by Texas Instruments. It features a single element with eight bidirectional channels configured as 8 x 1:1 switches. The device operates within a supply voltage range of 2.3 V to 3.6 V and supports a maximum low-level output current of 128 mA and a maximum high-level output current of -128 mA. It exhibits a maximum on-resistance of 7 Ohms and a maximum propagation delay of 250 ps. The component is housed in a 20-pin SOIC package, designed for surface mount installation, and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission through eight independent 1:1 switching channels
• Features low on-resistance to minimize signal attenuation during active states
• Supports operation with supply voltages ranging from 2.3 V to 3.6 V
• Includes undershoot protection capabilities for input signal integrity

Applications

• Portable equipment requiring low-voltage bus switching
• Consumer electronics utilizing 3.3 V logic systems
• Computing products needing efficient data routing
• Telecommunications infrastructure components

Procurement Notes

Verify the specific suffix 'PW' corresponds to the 20-pin wide SOIC package configuration when sourcing. Confirm that the device meets RoHS compliance requirements if restricted substances are mandated for the assembly process. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target application environment.

Selection Notes

Select this component when designing circuits that require low-voltage operation between 2.3 V and 3.6 V. It is suitable for applications demanding bidirectional data flow with minimal signal distortion. Consider the 20-pin SOIC package dimensions for PCB layout constraints. Evaluate the propagation delay and on-resistance against system timing requirements to ensure signal integrity is maintained.

Part Context

This part belongs to the SN74CBTLV3245A series of digital bus switches. It serves as a low-voltage alternative to standard bus transceivers, offering reduced power consumption. The series is designed for high-speed data transfer in portable and battery-operated devices. It complements other Texas Instruments logic families by providing efficient signal routing solutions.

Replacement Considerations

SN74CBTLV3245ADWR is a tape-and-reel version of the same functional device. SN74CBTLV3245ADW offers the identical functionality in a tube packaging format. Verify pin compatibility and package dimensions before substituting.
