74CB3Q3257RGYRG4

Overview

The SN74CB3Q3257RGYRG4 is a 4-bit one-of-two FET multiplexer/demultiplexer from the Texas Instruments CB3Q logic series. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data flow. The device features a propagation delay of 0.2 ns and a load capacitance of 30 pF. It is housed in a 16-VQFN package with dimensions of 4 mm length and 3.5 mm width, designed for surface mount installation. The component functions as a low-voltage high-bandwidth bus switch suitable for portable applications.

Feature Summary

• Supports bidirectional data transmission between two channels
• Operates as a low-voltage high-bandwidth bus switch
• Features fast signal switching capabilities

Applications

• Portable equipment requiring low power consumption
• Battery-powered systems utilizing low-voltage logic
• High-speed data routing in compact electronic devices

Procurement Notes

Verify the specific suffix RGYRG4 against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm moisture sensitivity level requirements for your assembly process. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a 4-bit multiplexer is needed with a 0.2 ns propagation delay. It is appropriate for designs requiring operation between 2.3 V and 3.6 V. Consider the 16-VQFN package size if board space is limited. Verify that the bidirectional nature of the switch meets the signal flow requirements of the target circuit design.

Part Context

This part belongs to the SN74CB3Q3257 family of 4-bit one-of-two FET multiplexers. It is manufactured by Texas Instruments under the CB3Q logic series. The device is distinct from similar parts like the SN74CBTLV3257 due to its specific Q-series automotive-grade qualification and packaging options. It serves as a bus switch solution for low-voltage digital systems.

Replacement Considerations

The PI3B3257ZHDEX from Diodes Incorporated is listed as a similar replacement option. Verify functional equivalence regarding voltage ranges and package dimensions before substitution.
