Overview
The SNJ54HC541FK is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a military temperature range from -55°C to +125°C. The device features high-current outputs capable of driving up to 6 mA at 5 V, low input current of 1 µA maximum, and typical propagation delay of 10 ns. It utilizes a data flow-through pinout configuration in a 20-pin LCCC package.
Feature Summary
- Octal non-inverting buffers and line drivers with 3-state outputs
- Wide operating voltage range from 2 V to 6 V
- High-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads
- Data flow-through pinout facilitates printed circuit board layout
Applications
- LEDs
- Servers
- PCs and Notebooks
- Wearable Health and Wellness Devices

Procurement Notes
Verify the specific ordering suffix FK corresponds to the 20-pin LCCC package. Confirm RoHS status as No for this military-grade variant. Ensure the supplier provides traceability documentation suitable for the -55°C to +125°C operating temperature range required by the SN54 series specifications.
Selection Notes
Select this component when military-grade temperature stability (-55°C to +125°C) is required alongside HC logic performance. The LCCC package is suitable for applications demanding robust surface mounting without leads. Verify that the system design accommodates the dual output enable inputs (OE1 and OE2) which must both be low to activate the outputs.
Part Context
This part belongs to the SNx4HC541 family of octal buffers and line drivers. The SN prefix indicates military-grade qualification compared to the commercial SN74 variants. The FK suffix specifically denotes the 20-lead Ceramic Leadless Chip Carrier package, distinguishing it from SOIC, PDIP, or CDIP options available within the same logical family.

FAQ
How are the outputs controlled?
The 3-state outputs are controlled by two independent output-enable inputs (OE1 and OE2). If either OE1 or OE2 is high, all eight outputs enter a high-impedance state.
What is the recommended handling precaution?
Texas Instruments recommends handling the integrated circuit with appropriate electrostatic discharge (ESD) precautions to prevent damage ranging from subtle performance degradation to complete failure.
