SN74CBTLV3257D

Overview

The SN74CBTLV3257D is a low-voltage 4-bit 1-of-2 FET multiplexer/demultiplexer from the CBTLV logic series. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data flow. The device is housed in a 16-pin SOIC-Narrow package with surface mount installation. It functions as a bus exchanger with enable-low control logic, designed for applications requiring efficient signal routing in compact electronic systems.

Feature Summary

• Integrates four independent single-pole double-throw (SPDT) switches into a single package
• Utilizes FET technology to provide low on-resistance and high bandwidth performance
• Supports bidirectional data transmission between source and destination buses

Applications

• Portable equipment requiring low power consumption
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing signal path management

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component meets the required operating temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this component for designs requiring a 4-channel multiplexer compatible with 3.3 V logic families. The CBTLV series offers superior switching characteristics compared to standard CMOS alternatives. Consider the SOIC-16 footprint constraints during PCB layout planning to ensure adequate clearance and thermal management for the selected package type.

Part Context

This part belongs to Texas Instruments' CBTLV family of low-voltage analog switches. The family is engineered for portable applications where power efficiency and signal integrity are critical. The SN74CBTLV3257D specifically provides four channels of switching capability, distinguishing it from lower-density variants in the same logical series.

Replacement Considerations

The SN74CBTLV3257DR serves as a reel-based replacement for the tape-and-reel version of the same die. Cross-reference with other CBTLV series devices only if pinout compatibility and electrical specifications match exactly.
