The 54F181LM/B is a synchronous 16-bit to 32-bit multiplier manufactured by Rochester Electronics. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to +125°C. The component is housed in a LCC-24 package and processes four bits per element.
Verify the specific revision level and manufacturing date code upon receipt, as Rochester Electronics components are often sourced from original manufacturer wafers or recreated IP. Confirm that the LCC-24 package dimensions match your PCB footprint exactly. Ensure the supply voltage remains strictly within the 4.5V to 5.5V range during operation to maintain functional integrity and avoid electrical overstress conditions.
Select this component when a dedicated synchronous multiplier is required for 16-bit to 32-bit operations in harsh environments. The LCC-24 package offers a compact solution for space-constrained designs. Consider the -55°C to +125°C operating range if the application involves extreme thermal conditions where standard commercial grade parts would fail. Verify interface timing requirements against system clock speeds.
