SN74CBTLV3257RSVR

Overview

The SN74CBTLV3257RSVR is a low-voltage, four-bit single-pole double-throw (SPDT) field-effect transistor (FET) multiplexer and demultiplexer manufactured by Texas Instruments. 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 UQFN-16 surface-mount package with an operating temperature range from -40°C to +85°C. It belongs to the CBTLV logic series and functions as a signal switch for routing analog or digital signals.

Feature Summary

• Provides four independent SPDT switching channels for signal routing
• Supports bidirectional data transmission between ports
• Operates on a single power supply within the specified low-voltage range

Applications

• Portable consumer electronics requiring low-power signal switching
• Battery-powered devices utilizing low-voltage logic interfaces
• Mobile communication equipment signal path management

Procurement Notes

Verify the specific suffix 'RSVR' corresponds to the UQFN-16 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for applications requiring compact footprint solutions with low-voltage operation. Compare against other CBTLV series variants if different packaging options like SOIC or VQFN are preferred. Validate that the 2.3 V minimum supply voltage aligns with the system power rails.
