It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This device is a DECODER/LATCH capable of selecting arbitrarily one of eight outputs by three binary inputs A, B, and C, in this case, the selected output is at logic "low". Also, when ENABLE input G1 is set low or ENABLE input G2 is set high, selection is inhibited regardless of other input signals and all the outputs are at high. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
