It has the same high speed performance of LSTTL combined with true CMOS low power consumption. A BCD code applied to the four inputs A-D selects one of ten decimal outputs Y0-Y9, which goes low to fifteen gives a high level at all outputs. This device also can be used as a 3-to-8 LINE DECODER, when the D input is assigned as a disable input. This device is useful for code conversion, address decoding, memory selection, demultiplexing, or readout decoding. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
