SNJ54HC133FK is listed in the Inverter Gates range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC GATE NAND. Review the specifications below when checking this part for your BOM.
The SNJ54HC133FK is a high-speed CMOS logic component manufactured by Texas Instruments, classified under the HC/UH series. It functions as a 13-input positive-NAND gate housed in a 20-lead ceramic Quad Flat Pack (LCC) package. The device supports an operating temperature range from -55°C to 125°C and features registered outputs with a ripple clock output (RCO). It is designed for military-grade reliability and harsh environment applications requiring robust digital signal processing capabilities.
Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-LCCC ceramic package. Confirm that the lead-free status and RoHS compliance meet current regulatory requirements for the intended deployment environment before finalizing procurement orders.
Select this component when a high fan-in NAND function is required in space-constrained military or industrial designs. The ceramic LCC package offers superior thermal stability compared to plastic alternatives. Consider the registered output feature if noise immunity and data retention are critical for the system architecture.
This part belongs to the SN54HC family of high-speed CMOS logic devices produced by Texas Instruments. The 'J' or 'FK' suffix typically denotes a military-grade qualification and a ceramic flat pack or LCC package variant. These components are engineered for performance in environments where standard commercial parts would fail due to extreme temperatures or radiation exposure.
Public confirmed substitute part numbers: SNJ54HC133J, SNJ54HC133W.
