The 54ACT11004FK/B is a hex inverter manufactured by Rochester Electronics, LLC. It belongs to the ACT series and features TTL-compatible inputs. The device is housed in a CQCC20 package with a ceramic, metal-sealed cofired body material. It operates within a temperature range of -55 °C to 125 °C. The component contains one functional unit with complementary outputs.
Verify the specific lot code and manufacturing date against project requirements. Confirm that the ceramic package type meets mechanical stress and environmental sealing standards for the intended application. Ensure compatibility with existing PCB footprints designed for the CQCC20 form factor before finalizing procurement.
Select this component when high-temperature operation up to 125 °C is required. The ceramic package offers superior hermeticity compared to plastic alternatives. Verify that the complementary output requirement aligns with the circuit design needs for signal inversion applications.
Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductors. This part is derived from original manufacturer specifications but produced under Rochester's quality control processes. It serves as a replacement source for legacy systems requiring the 54ACT11004 specification.
Cross-reference with other 54ACT11004 variants from different manufacturers to ensure pinout and electrical parameter compatibility. Verify package dimensions match the existing assembly tooling.
