SN74ALVCH16269DLR

Universal Bus Functions Overview

The SN74ALVCH16269DLR is a 12-bit to 24-bit registered bus exchanger with 3-state outputs, manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features a maximum propagation delay of 5 ns at 3.3 V. The device provides ±24-mA output drive capability and incorporates bus hold on data inputs to eliminate the need for external pullup or pulldown resistors. It is housed in a 56-pin SSOP (DL) package.

Universal Bus Functions Feature Summary

• Registered bus exchange functionality allowing multiplexing and demultiplexing between two separate ports and a single port
• Active bus-hold circuitry maintains valid logic states on unused or undriven inputs without external components
• Synchronous control terminals ensure all transactions are synchronized with the clock input

Universal Bus Functions Applications

• Interface between synchronous DRAMs and high-speed microprocessors
• Multiplexing two sequential 12-bit words into a 24-bit word on the B port
• Demultiplexing 24-bit data back into two 12-bit words

Universal Bus Functions Procurement Notes

Verify the specific ordering suffix 'DLR' corresponds to the tape and reel packaging variant within the DL package type. Confirm that the component status aligns with current production data sheets, as availability may vary. Ensure the selected part matches the required operating temperature range of -40°C to 85°C for your application environment.

Universal Bus Functions Selection Notes

Select this component when a registered bus exchanger is required to interface 12-bit and 24-bit data paths. It is suitable for applications needing synchronous control of data flow between separate ports. Consider the 1.65-V to 3.6-V supply range and the 5-ns propagation delay for timing constraints. Verify that the 56-pin SSOP package fits the board layout requirements.

Universal Bus Functions Part Context

This device belongs to the Texas Instruments Widebus family of logic ICs. It is designed specifically for high-speed data transfer applications where bus width expansion or contraction is necessary. The registered nature of the bus exchanger allows for precise timing control of data storage and retrieval.
