Frequently Asked Questions
What is the logic function of the SN74159NE4?
The SN74159NE4 is a 4-line to 16-line decoder and demultiplexer that activates one of 16 open-collector outputs based on the 4-bit binary input address, with active-low enable inputs to gate the device.
What type of outputs does the SN74159NE4 have?
The SN74159NE4 features open-collector outputs, which allow multiple devices to share a common bus and require external pull-up resistors; this enables wire-AND logic and flexible interfacing to different voltage levels.
What package does the SN74159NE4 come in?
The SN74159NE4 is housed in a 24-pin DIP (Dual In-Line Package) through-hole package, which is well suited for prototyping, educational use, and production in systems where through-hole mounting is preferred.
Is the SN74159NE4 compatible with TTL logic levels?
Yes, the SN74159NE4 belongs to the TTL logic family and accepts standard TTL input levels, making it directly compatible with 74-series logic ICs, microcontrollers with TTL-level I/O, and legacy digital systems.
What is the maximum sink current per output of the SN74159NE4?
Each output of the SN74159NE4 can sink a maximum of 16mA (I_OL), which is sufficient for driving small relays, LED indicators, and standard TTL or CMOS logic inputs in typical decoder applications.
