This 8-BIT D-Type latches is controlled by a latch enable input (LE) and output enable input (OE). While the LE input is held at a high level, the Q outputs will follow the data input precisely. When LE is taken low, the Q outputs will be latched precisely at the logic level of D input data. While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and while is at high level the outputs will be in a high impedance state. The 3-State output configuration and the wide choice of outline make bus organized system simple. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
