SN74CBT162292DL

Overview

The SN74CBT162292DL is a 12-bit 1-of-2 multiplexer/demultiplexer manufactured by Texas Instruments. It features internal pull-down resistors on the output ports to ensure defined logic states when disconnected. The device operates as a single circuit with 12 independent channels, facilitating data routing between two sets of lines. It is designed for low-voltage applications and utilizes a surface-mount package suitable for automated assembly processes in electronic systems requiring signal switching.

Feature Summary

• Integrates internal pull-down resistors on output ports to maintain stable logic levels during disconnection
• Functions as a 12-bit 1-of-2 multiplexer or demultiplexer for bidirectional data routing
• Supports low-voltage operation within specified supply ranges

Applications

• Data bus switching in portable electronic devices
• Signal routing in consumer electronics systems
• Multiplexing applications in industrial control interfaces

Procurement Notes

Verify the specific datasheet revision and manufacturing date code upon order confirmation. Confirm that the internal pull-down resistor specifications align with the system's idle state requirements. Ensure the operating voltage range matches the target application's power supply constraints before finalizing procurement decisions.

Selection Notes

Select this component when a 12-channel switching solution with defined idle states is required. The integrated pull-down resistors eliminate the need for external components in many designs. Consider the package type and thermal characteristics relative to the PCB layout constraints and available space in the final assembly.

Part Context

This part belongs to the SN74CBT series of low-voltage analog switches and multiplexers from Texas Instruments. The series is characterized by high speed and low on-resistance, making it suitable for modern digital systems.
