SNJ54F04FK is listed in the Inverter Gates range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC HEX INVERTER. Review the specifications below when checking this part for your BOM.
The SNJ54F04FK is a hex inverter manufactured by Texas Instruments, featuring six independent inverters that perform the Boolean function Y = A with a bar. It is characterized for operation over the full military temperature range of -55 °C to 125 °C. The device operates on a supply voltage (VCC) ranging from 4.5 V to 5.5 V. High-level output voltage (VOH) is typically 3.4 V at VCC = 4.5 V and IOH = -1 mA. Low-level output voltage (VOL) is typically 0.5 V at VCC = 4.5 V and IOL = 20 mA. Switching characteristics at VCC = 5 V and CL = 50 pF show typical propagation delays (tPLH/tPHL) of 3.3 ns and 2.8 ns respectively.
Verify the specific ordering suffix FK corresponds to the LCCC package configuration. Confirm RoHS exemption status as indicated in the packaging data. Ensure the procurement channel provides QML certified parts if military specifications are required. Validate the operating temperature range matches the application's environmental constraints before finalizing orders.
Select this component when six independent inverters are needed for military-grade environments. Compare against SN74F04 variants if commercial temperature ranges suffice. Consider the LCCC package requirements for board layout compatibility. Verify input/output electrical characteristics align with system voltage levels and load conditions.
This part belongs to the SN54F04 family of hex inverters. It is distinct from the SN74F04 due to its extended military temperature rating. The FK suffix denotes the leadless ceramic chip carrier package. It serves as a fundamental building block for digital logic circuits requiring signal inversion.
SNJ54F04J and SNJ54F04W are confirmed substitutes offering identical functionality in CDIP and CFP packages respectively.
