SN74CBT3257CPW

Overview

The SN74CBT3257CPW is a 4-bit 1-of-2 FET multiplexer/demultiplexer from Texas Instruments' CBT logic series. It features four independent switches in a 16-pin TSSOP package, supporting a supply voltage range of 4 V to 5.5 V. The device operates within a temperature range of -40°C to +85°C and is designed for surface-mount installation.

Feature Summary

• Provides four independent bidirectional data paths for signal routing
• Utilizes FET technology for low on-resistance switching
• Compatible with standard TTL logic levels

Applications

• Data line switching in digital systems
• Signal path selection in communication interfaces
• Bus exchange applications requiring high-speed data transfer

Procurement Notes

Verify the specific suffix 'CPW' against the manufacturer's current datasheet to confirm the exact package variant and tape/reel specifications. Ensure the ordering part number matches the required 16-pin TSSOP configuration and voltage ratings before procurement.

Selection Notes

Select this component when a 4-channel multiplexer is required for 5V logic applications. Consider the CBTLV3257 series if lower voltage operation below 3.6V is necessary. Verify that the TSSOP-16 footprint aligns with the PCB design constraints.

Part Context

This part belongs to the SN74CBT3257 family of low-voltage CMOS quad bus switches. It serves as a compact solution for managing multiple data lines in space-constrained designs, offering a balance between channel count and package size compared to single-channel alternatives.

Replacement Considerations
