SN74CBTS16212DL

Overview

The SN74CBTS16212DL is a high-speed TTL-compatible FET bus-exchange switch manufactured by Texas Instruments. It provides 24 bits of bus switching or exchanging capabilities with integrated Schottky diodes on the I/Os for clamping. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports data exchanging between four signal ports via data-select inputs. It features low ON-state resistance and is housed in a 56-pin SSOP package, suitable for industrial temperature ranges from -40 °C to +85 °C.

Feature Summary

• Provides 24-bit high-speed TTL-compatible bus switching or exchanging functionality
• Integrates Schottky diodes on I/Os for effective clamping protection
• Supports data exchanging between four signal ports via dedicated data-select inputs
• Features low ON-state resistance for efficient signal transmission

Applications

• High-speed data routing in communication systems
• Bus exchange applications requiring multiple signal port interconnection
• Industrial control systems operating within specified temperature ranges

Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the 56-pin SSOP package and industrial temperature grade (-40°C to +85°C). Confirm that the component includes the required Schottky diode clamping feature as documented in the official Texas Instruments datasheet for this part number. Ensure compatibility with 5V logic levels before integration.

Selection Notes

Select this component when a 24-bit bus switch or 12-bit bus exchanger is required with integrated input protection. The SN74CBTS16212DL is appropriate for designs needing TTL compatibility and low ON-resistance. Consider the 56-pin SSOP footprint constraints and the need for external data-select control signals for multi-port configuration.

Part Context

This device belongs to the SN74CBT series of high-speed CMOS logic components. It is specifically designed as a bus-exchange switch, differing from standard bus switches by its ability to route data between multiple ports using select lines. The inclusion of Schottky diodes distinguishes it from non-clamped variants in the same family.

Replacement Considerations

The SN74CBTD3306D is a different component (2-element, 8-pin) and is not a direct replacement. Verify cross-reference availability through official TI channels for equivalent 24-bit bus exchangers.
