Overview
The SNJ54BCT244FK is an octal buffer and line driver with three-state outputs, manufactured by Texas Instruments. It utilizes state-of-the-art BiCMOS technology to significantly reduce quiescent current (ICCZ). The device features PNP inputs that reduce DC loading and includes ESD protection exceeding 2000 V per MIL-STD-883C, Method 3015. It operates over the full military temperature range of -55 °C to 125 °C. The package is a 20-pin Ceramic Chip Carrier (FK) with a leadless design.

Procurement Notes
Verify the specific ordering suffix FK corresponds to the 20-pin LCCC package. Confirm RoHS status as No for this military-grade part. Check active production status and tube packaging quantity of 55 units. Ensure compatibility with MIL-STD-883C requirements if applicable.
Selection Notes
Select this component for applications requiring high-speed octal buffering in military environments. The BCT series offers improved performance over standard logic families. Consider the ceramic package for thermal stability and reliability in harsh conditions compared to plastic alternatives.
Part Context
This part belongs to the SN54BCT244 family, which includes variants like SNJ54BCT244J and SNJ54BCT244W. It is designed to work alongside other BCT devices such as the 'BCT240 and 'BCT241, providing options for inverting and non-inverting outputs with symmetrical or complementary output-enable inputs.

FAQ
What is the organization of the SNJ54BCT244FK?
It is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs.
How does the device handle data when OE is low?
When OE is low, the device passes data from the A inputs to the Y outputs.
What happens to the outputs when OE is high?
When OE is high, the outputs are in the high-impedance state.
