This device is useful for code C2MOS technology. conversion, address decoding, memory selection, A BCD code applied to the four inputs A-D selects demultiplexing, or readout decoding. one of ten decimal outputs Y0 - Y9, which goes All inputs are equipped with protection circuits low to fifteen gives a high level at all outputs. This against static discharge and transient excess device also can be used as a 3 to LINE voltage.
