Key Features
- 4-to-16 line fully decoded outputs cover all 16 binary combinations, enabling single-chip address decoding for memory and I/O expansion
- 16 mA active-low output drive current sinks standard TTL and CMOS logic loads directly without additional buffer transistors
- Dual active-low enable inputs allow cascading multiple SN74154 devices or gating the decoder output with a strobe signal for bus-oriented designs
Applications
The SN74154NE4 is a classic address decoder used in microprocessor-based systems to select one of up to 16 memory banks, I/O ports, or peripheral chips from a 4-bit address bus. Its demultiplexer function also enables routing a single input data line to any one of 16 output channels, making it suitable for display multiplexing, relay driver selection, and communication channel switching. The through-hole DIP-24 package facilitates use in breadboard prototypes, educational kits, and legacy industrial control systems requiring socketed component replacement.

Frequently Asked Questions
How many output lines does the SN74154NE4 decoder provide?
The SN74154NE4 provides 16 active-low output lines decoded from a 4-bit binary input, with only one output driven low at a time corresponding to the selected binary code, making it a complete 4-to-16 line decoder in a single package.
Can the SN74154NE4 be used as a demultiplexer as well as a decoder?
Yes, the SN74154NE4 can function as a 1-to-16 demultiplexer by using one of its two enable inputs as the data input, routing a single data signal to any one of 16 output lines as selected by the 4-bit address inputs.
What is the output drive current of the SN74154NE4?
The SN74154NE4 has a maximum output low current (I_OL) of 16 mA per output pin, allowing it to directly drive TTL and CMOS logic inputs, indicator LEDs with current-limiting resistors, and relay driver transistor bases.
What package does the SN74154NE4 use and is it RoHS compliant?
The SN74154NE4 is housed in a 24-pin Plastic Dual In-Line Package (PDIP, JESD-30 code R-PDIP-T24). The 'E4' suffix and Pb-free code confirm it is lead-free and meets JESD-609 e4 halogen-free, RoHS-compliant material standards.
