A binary code stored in the four input latches (A to D) provides a high level at the selected one of sixteen outputs excluding the other fifteen outputs, when the inhibit input (INHIBIT) is held low. When the inhibit input (INHIBIT) is held high, all outputs are kept low level, while the latch function is available. The data applied to the data inputs are transferred to the Q outputs of latches when the strobe input is held high. When the strobe input is taken low, the information data applied to the data input at a time is retained at the output of the latches. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
