SN74CBTLV3257PWR

Overview

The SN74CBTLV3257PWR is a low-voltage FET-based multiplexer/demultiplexer from the Texas Instruments CBTLV series. It features four independent 1-of-2 switches in a 16-pin TSSOP package. The device operates on a single supply voltage ranging from 2.3 V to 3.6 V. It supports surface mount installation and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent low-voltage FET switches for signal routing
• Supports bidirectional data transmission with low on-resistance characteristics
• Provides high bandwidth performance suitable for high-speed digital applications

Applications

• Portable equipment requiring low power consumption
• Cellular phones and wireless communication devices
• LCD driver circuits
• Video signal switching systems

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status aligns with current environmental regulations for the target market. Ensure the ordering part number matches the exact logic family and pinout configuration specified in the official datasheet to avoid integration errors.

Selection Notes

Select this component when designing circuits that require multiple low-voltage signal paths within a compact footprint. The TSSOP-16 package offers a balance between pin density and thermal management. Consider the operating voltage limits and temperature range to ensure compatibility with the system's power supply rails and environmental conditions.

Part Context

This device belongs to the SN74CBTLV3257 family, which includes variants such as SN74CBTLV3257DR and SN74CBTLV3257RGYR. These parts share identical logical functionality but differ in physical packaging types, including SOIC, VQFN, and TSSOP configurations. The family is designed for portable electronics where space and power efficiency are critical constraints.

Replacement Considerations

SN74CBTLV3257PW is a manufacturer-recommended alternative available in the same TSSOP-16 package. Other package variants like SN74CBTLV3257DR (SOIC) or SN74CBTLV3257RGYR (VQFN) may serve as functional substitutes if board layout adjustments are permissible.
