Procurement Notes

Verify the component status as this part may be obsolete or subject to discontinuation notices. Confirm that the specific ordering code matches the required package type and temperature range. Ensure compatibility with existing JEDEC standards and voltage requirements before finalizing procurement decisions.

Selection Notes

Select this component for high-speed data transmission requiring precise signal integrity through integrated termination. Consider the 18-bit width and registered output capabilities for complex bus architectures. Evaluate the low inductance design benefits for noise-sensitive environments and ensure the 3-state functionality aligns with system control logic.

Part Context

This component belongs to the AVCM series of universal bus drivers designed for high-performance digital applications. It serves as a registered driver solution, providing latched outputs controlled by clock and latch enable inputs. The integration of termination resistors distinguishes it from standard buffer devices, offering enhanced signal quality for memory interfaces.

Replacement Considerations

Consult official replacement lists for discontinued parts. Verify pinout and electrical specifications against potential substitutes to ensure functional equivalence without redesigning the host circuit board.

FAQ

How does the 74AVCM162835 handle partial power-down scenarios?

The device supports partial power-down applications using IOFF circuitry, which disables outputs to prevent damaging backflow currents when powered down.

What is the function of the LE input?

The Latch Enable (LE) input controls the latching of data from the A inputs to the internal register, allowing data to be held stable at the outputs independent of the clock input.
