SN74CBT16212ADLR

Overview

The SN74CBT16212ADLR is a 56-pin SSOP digital bus switch and exchanger from Texas Instruments. It provides 24 bits of high-speed TTL-compatible switching or exchanging. The device operates as a 24-bit bus switch or a 12-bit bus exchanger utilizing three data-select terminals (S0, S1, S2). It supports a supply voltage range of 4 V to 5.5 V with an operating temperature range of -40°C to +85°C. Key electrical parameters include a maximum on-state resistance of 12 Ω at 4.5 V and a propagation delay of 0.35 ns at 5 V.

Feature Summary

• Provides 24-bit high-speed TTL-compatible bus switching functionality
• Configurable as a 12-bit bus exchanger for data routing between four signal ports
• Features low on-state resistance for minimal signal propagation delay
• Includes ESD protection exceeding JESD 22 standards

Applications

• High-speed data bus switching applications
• Data exchanging between multiple signal ports
• TTL-compatible logic interface circuits

Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP package configuration required for your design. Confirm that the -40°C to +85°C industrial temperature rating aligns with your operational environment specifications. Ensure all unused control inputs are properly terminated to VCC or GND to maintain stable device operation.

Selection Notes

Select this component when a 24-bit wide bus switch or a 12-bit bidirectional data exchanger is required. The device is suitable for systems needing TTL-compatible input levels and low on-resistance switching. Consider the 56-pin SSOP package dimensions and thermal characteristics during PCB layout planning.

Part Context

This part belongs to the Widebus family of Texas Instruments. It is designed to handle large data widths efficiently within a single integrated circuit. The device integrates FET-based switches controlled by dedicated select lines to manage complex data routing tasks in digital systems.
