SN74CBTLVR16292DL

Overview

The SN74CBTLVR16292DL is a low-voltage 12-bit 1-of-2 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3V to 3.6V and features internal pull-down resistors on all inputs and outputs. The device utilizes a 56-pin LQFP package with a 0.5mm pitch, suitable for surface-mount applications. It supports bidirectional data transmission and includes an active-low enable input to control signal flow.

Feature Summary

• Integrates twelve independent 1-of-2 FET switches for high-density signal routing
• Includes internal pull-down resistors on all I/O lines to define logic states during power-up or floating conditions
• Supports bidirectional data transfer between two buses controlled by a single enable pin

Applications

• High-speed data bus switching in portable electronic devices
• Signal routing in consumer electronics requiring low-voltage operation
• Multiplexing applications in embedded systems with limited pin counts

Procurement Notes

Verify the specific suffix 'DL' corresponds to the 56-pin LQFP package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the design accommodates the 0.5mm pitch requirements for PCB layout. Check for any recent product change notices regarding assembly materials or manufacturing location changes.

Selection Notes

Select this component for designs requiring 12-channel multiplexing at low voltages. The internal pull-downs simplify external circuitry compared to variants without them. Compare against the standard SN74CBT16292 if 5V operation is required instead of the 2.3V-3.6V range. Consider the physical footprint constraints of the 56-pin LQFP package relative to available board space.

Part Context

This part belongs to the SN74CBT series of analog switches and multiplexers from Texas Instruments. It is functionally similar to the SN74CBTLV16292 but distinguished by its specific package type (LQFP) and suffix designation. The series is designed for low-power, high-speed applications in mobile and consumer markets.

FAQ

What is the function of the internal pull-down resistors?

The internal pull-down resistors ensure that all inputs and outputs are held at a defined logic low state when the device is powered down or when signals are floating, preventing undefined states.

Is the data flow bidirectional?

Yes, the SN74CBTLVR16292DL supports bidirectional data transfer, allowing signals to pass from either bus A to bus B or vice versa when enabled.
