SN74CBTLV3257RGYR

Overview

The SN74CBTLV3257RGYR is a low-voltage, quad 1-of-2 multiplexer/demultiplexer from the Texas Instruments CBTLV series. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data flow. The device features an active-low enable control input and is housed in a 16-pin HVQCCN package with dimensions of 4 mm length. It has a load capacitance of 30 pF and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports bidirectional data transmission for flexible signal routing
• Features active-low enable control for precise switching management
• Designed for low-voltage operation compatible with modern digital systems

Applications

• Portable consumer electronics requiring low power consumption
• Battery-powered devices utilizing single-supply logic
• High-density board layouts needing compact surface-mount packaging

Procurement Notes

Verify the specific suffix RGYR corresponds to the 16-VQFN package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the ordering part number matches the exact pinout and electrical specifications required by the design schematic before finalizing procurement.

Selection Notes

Select this component when a quad 1-of-2 mux/demux is needed for low-voltage applications between 2.3 V and 3.6 V. It is suitable for designs prioritizing small footprint solutions due to its QFN package. Consider the bidirectional capability if signal directionality needs to be dynamically controlled via the enable pin.

Part Context

This part belongs to the SN74CBTLV3257 family of low-voltage CMOS logic devices. It shares functional similarities with other members like the SN74CBTLV3257PWR but differs in physical packaging. The RGYR suffix specifically denotes the 16-pin VQFN form factor, distinguishing it from TSSOP or UQFN variants within the same logical family.

Replacement Considerations

The 74CBTLV3257RGYRG4 is a documented equivalent variant within the same product line.
