Frequently Asked Questions

What decoding function does the SNJ54AS138J perform?

The SNJ54AS138J decodes a 3-bit binary input into one of eight mutually exclusive active-low outputs, making it ideal for address decoding in memory systems and I/O port selection in microprocessor bus designs.

How many enable inputs does the SNJ54AS138J have?

The device has three enable inputs: two active-low (G1 and G2A) and one active-high (G2B). All three must be in their correct state simultaneously for the decoder to operate, enabling easy chip-select and cascade control.

What temperature range does the SNJ54AS138J support?

The SNJ54AS138J is rated from -55°C to 125°C under military temperature specifications, making it suitable for avionics, defense ground systems, and space payload applications in extreme environments.

What is the output sink current of the SNJ54AS138J?

The decoded active-low outputs can sink up to 20 mA (IOL), providing sufficient drive capability to directly enable chip-select inputs of memory ICs, peripheral controllers, and other logic devices in the decoded address space.
