SN74CBT16292DL

Overview

The SN74CBT16292DL is a 12-bit 1-of-2 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single power supply ranging from 4.5V to 5.5V and features an industrial operating temperature range of -40°C to +85°C. The device is housed in a 56-pin TSSOP package with a width of 0.40 inches (10.30mm). It includes internal pull-down resistors on all inputs to ensure defined logic states when disconnected.

Feature Summary

• Integrates twelve independent 1-of-2 switches within a single package for high-density signal routing
• Includes internal pull-down resistors on all input lines to maintain stable logic levels during idle states
• Supports bidirectional data flow between A and B ports controlled by the select input

Applications

• High-speed data bus switching in computer systems
• Signal routing in telecommunications equipment
• Multiplexing applications in industrial control systems

Procurement Notes

Verify the specific suffix 'DL' against current manufacturer documentation, as availability may vary compared to the 'DGVR' variant. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the ordering quantity matches the standard packaging configuration provided by the distributor.

Selection Notes

Select this component for designs requiring 12-channel switching at 5V logic levels. Compare against the SN74CBTLV16292 series if lower voltage operation below 3.6V is required. Verify that the TSSOP-56 footprint aligns with the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the Texas Instruments 74CBT series of low-voltage CMOS analog switches. These devices are designed for high-speed data transmission and offer low on-resistance and minimal signal distortion. The family provides various channel counts and package options to suit different density and performance needs in digital signal processing.

Replacement Considerations

The SN74CBTLV16292VR is listed as a manufacturer-recommended alternative. Note that the LV variant supports a lower voltage range (2.3V to 3.6V) compared to the standard 5V operation of the SN74CBT16292DL. Verify voltage compatibility before substitution.
