SN74CBT16212CDLR

Overview

The SN74CBT16212CDLR is a digital bus switch IC manufactured by Texas Instruments. It features a 12-bit configuration with a 2:2 bidirectional switching architecture, housed in a 56-pin TSSOP package. The device operates on a single power supply ranging from 4.0V to 5.5V. Key electrical specifications include a maximum on-resistance of 12 Ohms and a maximum propagation delay of 250 ps. It supports surface-mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 12 channels of bidirectional data switching with a 2:2 configuration for efficient bus management.
• Features low on-resistance to minimize signal attenuation across the data path.
• Ensures high-speed signal integrity through low propagation delay characteristics.

Applications

• High-speed data bus isolation in computing systems
• Signal routing in consumer electronics interfaces
• Data line protection in industrial control modules

Procurement Notes

Verify the specific suffix 'CDLR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required pinout and thermal performance specifications for your PCB layout. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement.

Selection Notes

Select this component when a 12-channel bidirectional switch with a 2:2 topology is required for 5V logic systems. Compare the 12 Ohm on-resistance and 250 ps delay against system bandwidth needs. Consider the 56-TSSOP package dimensions for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the SN74CBT1621xC series of bus switches. These devices are designed for high-density applications requiring multiple independent switching channels. The series offers a balance of speed and drive capability suitable for general-purpose digital signal routing in standard voltage domains.

Replacement Considerations

Check for direct substitutes such as the SN74CBT16212CDGGR or other variants within the SN74CBT1621x family that share the same functional pinout and electrical characteristics but differ in packaging or reel specifications.
