SN74CBT16292DLR

Overview

The SN74CBT16292DLR is a 12-bit 1-of-2 multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single power supply ranging from 4.5V to 5.5V and features internal pull-down resistors. The device is housed in a 56-pin SSOP package with an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates twelve independent 1-of-2 FET switches for signal routing
• Includes internal pull-down resistors on all data lines
• Supports bidirectional data flow between A and B buses

Applications

• High-speed data bus switching applications
• Signal path selection in digital systems
• Multiplexing control logic circuits

Procurement Notes

Verify the specific suffix 'DLR' against the manufacturer's current product status, as availability may vary. Confirm that the 56-pin SSOP package aligns with your PCB footprint requirements. Ensure the 4.5V to 5.5V voltage range matches your system's power supply specifications before finalizing procurement.

Selection Notes

Select this component when a high-density 12-channel multiplexer is required within a standard 5.0V logic environment. The integrated pull-down resistors simplify design by eliminating external components. Consider the 56-pin SSOP package constraints regarding board space and thermal dissipation during the layout phase.

Part Context

This part belongs to the Texas Instruments 74CBT series, designed for low-voltage and high-speed applications. It serves as a specialized signal switch solution within the broader category of logic ICs, specifically targeting mux/demux functions for complex digital interconnects.

Replacement Considerations

The SN74CBT16292DGVR is a recommended manufacturer replacement offering identical functionality in a TVSOP package. Verify pin compatibility and package dimensions before substitution.
