Overview
The 54F10LMQB is a triple 3-input NAND gate integrated circuit manufactured by National Semiconductor. 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 device features three independent logic circuits, each with three inputs. Output current capabilities include 1mA for high state and 20mA for low state. Maximum quiescent current is specified at 7.7 mA. The component is housed in a 20-pin LCCC package measuring 8.89x8.89 mm.
Feature Summary
- Triple 3-input NAND logic functionality
- Extended industrial temperature operation capability
- Ceramic leadless chip carrier packaging
Applications
- Digital logic processing systems
- Industrial control environments requiring wide temperature tolerance
- Military or aerospace electronic assemblies
Procurement Notes
Verify the manufacturer designation as National Semiconductor, now part of Texas Instruments, to ensure authenticity. Confirm the specific suffix 'LMQB' corresponds to the required ceramic LCCC package variant rather than plastic alternatives. Check for RoHS compliance status if applicable to your regulatory requirements. Ensure the source provides valid traceability documentation for components intended for critical applications.
Selection Notes
Select this component when a triple 3-input NAND gate is required in a ruggedized ceramic package. The 54-series designation indicates military-grade performance specifications compared to commercial 74-series equivalents. Consider the 20-pin LCCC form factor for surface mount applications requiring high thermal stability and hermetic sealing characteristics suitable for harsh environments.
Part Context
This part belongs to the 54F series of fast TTL logic gates. The 54F10 specifically denotes a triple 3-input NAND configuration. The LMQB suffix identifies the specific package type and material construction. This series is designed for high-speed digital switching applications where reliability under extreme conditions is paramount.
Replacement Considerations
The 74F10 is a commercial-grade equivalent but lacks the extended temperature range and potentially different packaging options. Verify pin compatibility and electrical specifications before substitution. Other 54F10 variants may exist with different package styles such as Cerpack.
