SN74CBTLV16292DL

Overview

The SN74CBTLV16292DL is a low-voltage 12-bit 1-of-2 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single power supply ranging from 2.3 V to 3.6 V and features internal pull-down resistors on all inputs. The device utilizes a 56-pin LQFP package with a 0.5 mm pitch, suitable for surface-mount applications. It supports bidirectional data transmission and includes an active-low output-enable control input.

Feature Summary

• Integrates twelve independent 1-of-2 FET switches within a single package
• Includes internal pull-down resistors on all input lines
• Supports bidirectional data flow between ports A and B

Applications

• Portable equipment requiring low-voltage signal routing
• Battery-powered systems utilizing single-supply operation
• High-density board designs necessitating compact packaging

Procurement Notes

Verify the specific suffix 'DL' corresponds to the 56-pin LQFP package configuration during procurement. Confirm that the required operating voltage range aligns with the 2.3 V to 3.6 V specification. Ensure compatibility with the internal pull-down resistor functionality if external termination is not utilized in the design.

Selection Notes

Select this component when a high-channel-count multiplexer is required in a low-voltage environment. The integrated pull-down resistors simplify input handling compared to variants lacking this feature. Consider the 56-pin LQFP footprint constraints against available PCB real estate and thermal dissipation requirements for dense layouts.

Part Context

This part belongs to the SN74CBT series of logic switches designed for low-voltage digital applications. It serves as a cost-effective solution for managing multiple signal paths in portable electronics. The device complements other Texas Instruments logic families by providing high-density switching capabilities within a small form factor.

Replacement Considerations

The SN74CBTLV16292DR is a pin-compatible alternative offered in a tape-and-reel package format. Verify package dimensions and moisture sensitivity levels before substituting.
