SN74CBT3251PW

Overview

The SN74CBT3251PW is a single FET multiplexer/demultiplexer from Texas Instruments, configured as one 8-to-1 channel switch. It operates within a supply voltage range of 4 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 14 ohms, a maximum propagation delay of 6.4 ns, and a maximum transition time of 6.8 ns. The device supports an operating temperature range from -40°C to +85°C and is housed in a 16-pin SOIC-Narrow package.

Feature Summary

• Provides high-speed signal routing via a single 8:1 multiplexing configuration.
• Utilizes FET technology for low on-resistance and efficient signal transmission.
• Supports standard 5 V logic systems with defined switching performance metrics.

Applications

• Data acquisition systems requiring signal selection
• Communication equipment interface switching
• Industrial control signal routing

Procurement Notes

Verify the specific suffix 'PW' corresponds to the SOIC-Narrow 16-pin package when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the supply voltage requirements align with the 4 V to 5.5 V operational range specified for this component variant.

Selection Notes

Select this component for applications requiring a single 8-channel FET switch within a 5 V logic environment. Compare against the SN74CB3Q3251 series if lower voltage operation (2.3 V to 3.6 V) is required instead. Consider the SN74CBTLV3251 for low-voltage applications below 3.6 V. Verify package compatibility between SOIC-Narrow and other available formats like SSOP or VQFN based on board layout constraints.

Part Context

This part belongs to the SN74CBT3251 family of FET multiplexers and demultiplexers manufactured by Texas Instruments. The family includes variants with different packaging options such as DR, DBQR, and RGYR, all sharing the same core 1-of-8 switching functionality. The PW suffix specifically denotes the surface-mount SOIC-Narrow 16-pin housing used for this specific orderable part number.

Replacement Considerations

Direct pin-compatible substitutes within the same family include SN74CBT3251DR, SN74CBT3251DBQR, and SN74CBT3251RGYR. These alternatives offer identical electrical characteristics but differ in physical package type. Cross-manufacturer equivalents like Toshiba TC7MB3251FK may require verification of pinout and electrical parameter alignment.
