This 8 bit D-Type latch is controlled by a latch enable input (LE) and an output enable input (OE). PIN CONNECTION AND IEC LOGIC SYMBOLS While the LE input is held at a high level, the Q outputs will follow the data inputs precisely. When the LE is taken low, the Q outputs will be latched precisely at the logic level of D input data. While the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state. Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can...
