Key Features
- 3-line to 8-line decoding with built-in address latch for reduced external component count
- 16-PDIP through-hole package for easy prototyping and hand-soldering applications
- Low-power Schottky LS logic family with 15 pF load capacitance for reliable high-speed switching
Applications
The SN74LS137N3 is widely used in address decoding for memory and I/O expansion in embedded systems and microprocessor designs. Its built-in address latch makes it ideal for demultiplexed bus architectures where address and data share the same lines. The 3-to-8 line decode capability also suits applications in LED matrix drivers, relay control banks, and channel selection circuits.

Frequently Asked Questions
What is the maximum output sink current of the SN74LS137N3?
The SN74LS137N3 has a maximum output low current (I(ol)) of 8 mA, making it suitable for driving standard TTL loads and small LED indicators directly.
Can the SN74LS137N3 be used for memory address decoding?
Yes, the SN74LS137N3 is an excellent choice for memory address decoding. Its 3-to-8 line decoder function with built-in address latch allows selection among up to 8 memory banks or I/O devices using only 3 address lines.
What package does the SN74LS137N3 use and what are its temperature limits?
The SN74LS137N3 comes in a 16-pin PDIP (Plastic Dual In-Line Package) and is rated for a commercial temperature range of 0°C to 70°C, suitable for most industrial and consumer applications.
Is the SN74LS137N3 RoHS compliant?
The SN74LS137N3 is marked as not RoHS compliant per its Reach Compliance Code. Designers requiring RoHS-compliant alternatives should look for SN74LS137 variants explicitly marked with a RoHS-compliant suffix.
