Overview
The SN74CB3Q3257PWR is a low-voltage, high-bandwidth bus switch manufactured by Texas Instruments. It functions as a 4-bit 1-of-2 FET multiplexer/demultiplexer within the SN74CB3Q series. The device operates on a single supply voltage ranging from 2.3 V to 3.6 V. It features an active-low enable input and supports bidirectional data transfer with no propagation delay skew between channels. The component is housed in a 16-pin TSSOP package and is designed for surface-mount installation.
Feature Summary
- Provides four independent SPDT switches for signal routing
- Supports bidirectional data flow without channel skew
- Operates with a single power supply source
Applications
- Portable equipment requiring low-voltage signal switching
- Battery-powered systems utilizing bus architecture
- High-speed data line multiplexing applications
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the design accommodates the specified operating temperature range of -40°C to +85°C for reliable performance in industrial environments.
Selection Notes
Select this component when designing circuits that require low-voltage operation between 2.3 V and 3.6 V. It is suitable for applications demanding high bandwidth and minimal signal distortion across multiple data lines. Consider the TSSOP-16 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability for surface-mount assembly processes.
Part Context
This part belongs to the SN74CB3Q automotive-grade logic family, which offers enhanced reliability compared to standard commercial variants. It serves as a functional equivalent to other 4-bit bus switches in the CBTLV and CBT series, providing similar switching capabilities with specific qualification standards for automotive and industrial durability requirements.
Replacement Considerations
SN74CB3Q3257PWRE4 is a verified lead-free variant of the same logical function and pinout. SN74CB3Q3257PWRG4 represents another compliant alternative within the same product family.
