+# 74HC154
+
+Arduino library for the 74HC154 4-to-16 line decoder/demultiplexer.
+
+
+## Description
+
+This library controls the 74HC154 4 to 6 line decoder. 
+With 4 IO lines one can select one of 16 output lines. 
+
+
+#### Related
+
+- https://github.com/RobTillaart/74HC138  (3 to 8 selector)
+- https://github.com/RobTillaart/74HC154  (4 to 16 selector)
+- https://github.com/RobTillaart/HC4051  (1x8 mux)

+- https://github.com/RobTillaart/HC4053  (3x2 mux)
+- https://github.com/RobTillaart/HC4067  (1x16 mux)
+
+
+## Interface
+
+```cpp
+#include "74HC154.h"
+```
+
+#### Constructor
+
+- **74HC154(uint8_t pin0, uint8_t pin1, uint8_t pin2, uint8_t pin3, uint8_t pinEnable = 255)** 
+set the 4 selection IO lines from pin numbers.
+Optionally set the enable pin, connect to E1 or E2, see datasheet.
+- **74HC154(uint8_t \* pins, uint8_t pinEnable = 255)** 
+set the 4 selection IO lines from an array.
+The pins array should have at least 4 elements.
+Optionally set the enable pin, connect to E1, see datasheet.
+
+
+#### Select line
+
+- **bool setLine(uint8_t line)** set line 0 .. 15. Returns false if out of range.
+- **uint8_t getLine()** returns 0 .. 15
+- **void nextLine()** selects the next line, wraps back to 0 if needed.
+- **void prevLine()** selects the previous line, wraps to 15 if needed.
+
+
+#### Enable
+
+Works only if enable line is set in constructor.
+
+- **void enable()** enables output / selection.
+- **void disable()** disables output / selection.
+- **bool isEnabled()** checks if line is enabled.
+
+
+## Future
+
+#### Must
+
+- improve documentation
+- get hardware to test
+
+#### Should
+
+
+#### Could
+
+
+#### Wont
