Inverter Gates datasheet and documents for SNJ54AS808BFK
Inverter Gates Overview
The SNJ54AS808BFK is a military-grade logic device containing six independent 2-input AND drivers. It operates within the full military temperature range of -55 °C to 125 °C and utilizes a 20-pin LCCC (FK) package. The component supports a supply voltage (VCC) from 4.5 V to 5.5 V, with typical propagation delays of 3.2 ns at 50 pF load. High capacitive-drive capability is provided, featuring output currents up to 48 mA.
Inverter Gates Feature Summary
- Contains six independent 2-input AND drivers for Boolean logic operations
- High capacitive-drive capability supporting heavy loads
- Military-qualified performance across the full -55 °C to 125 °C temperature range
Inverter Gates Applications
- Military and defense electronic systems
- Aerospace logic control circuits
- Harsh environment digital signal processing
Inverter Gates Procurement Notes
Verify that the specific ordering suffix FK corresponds to the Leadless Ceramic Chip Carrier package. Confirm QML certification status if required for defense contracts. Ensure the procurement documentation explicitly states the SNJ54AS808BFK part number to distinguish it from commercial variants or other package options like CDIP.
Inverter Gates Selection Notes
Select this component when six independent AND gates are required in a ruggedized environment. The SNJ54AS808BFK is suitable for applications demanding operation at extreme temperatures where standard catalog parts would fail. Consider the 20-pin LCCC footprint during PCB layout planning.
Inverter Gates Part Context
This device belongs to the Texas Instruments AS series, known for high-speed Schottky TTL technology. The 'SNJ' prefix indicates a military-qualified ceramic package variant, while the 'FK' suffix specifically designates the leadless ceramic chip carrier form factor. It serves as a specialized version of the broader SN54AS808B family.
Inverter Gates Replacement Considerations
Direct substitutes include SNJ54AS808BJ (CDIP package) and SN54AS808B (general military grade). Verify pin compatibility and package dimensions before swapping between FK and J packages.
