SN74CB3T3253DBQR

Overview

The SN74CB3T3253DBQR is a low-voltage FET multiplexer/demultiplexer manufactured by Texas Instruments. It features an octal configuration with one-of-eight selection, providing eight data inputs and one output. The device operates within a supply voltage range of 2.3V to 3.6V and supports bidirectional signal transmission. It is housed in a 16-pin SSOP package and is designed for applications requiring high-speed data routing with low on-resistance.

Feature Summary

• Provides one-of-eight multiplexing or demultiplexing functionality for efficient signal routing
• Supports bidirectional data flow between the single common terminal and multiple input/output terminals
• Operates reliably across a wide industrial temperature range from -40°C to +85°C

Applications

• Data acquisition systems requiring selective channel access
• Portable equipment utilizing low-voltage power supplies
• Communication protocols involving signal path switching

Procurement Notes

Verify the specific suffix 'DBQR' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required pin configuration and electrical characteristics defined in the latest datasheet revision before finalizing procurement.

Selection Notes

Select this component when a single-channel output must be dynamically routed from one of eight available sources. The low operating voltage range makes it suitable for battery-powered designs. Verify that the required on-resistance and leakage current specifications align with the system's signal integrity requirements.

Part Context

This part belongs to the SN74CB3T series of low-voltage bus switches and multiplexers. These devices are engineered to replace mechanical relays and other solid-state switches in portable applications. The series offers high bandwidth and low power consumption, making them ideal for modern electronic systems requiring efficient signal management.

Replacement Considerations

Check for direct substitutes such as the SN74CBTLV3251DBQR, which shares similar multiplexing functions but may differ in package type or specific electrical parameters. Always cross-reference the pinout and functional truth tables to ensure compatibility during replacement.
