It is ideal for low power and highspeed 3.3V applications; it can be interfaced to 5Vsignal environment for both inputs and outputs.These 16 bit D-TYPE latches are byte controlledby two latch enable inputs (nLE) and two outputenable inputs(OE).While the nLE input is held at a high level, the nQoutputs will follow the data input precisely.When the nLE is taken LOW, the nQ outputs willbe latched precisely at the logic level of D inputdata.While the (nOE) input is low, the nQ outputs will bein a normal logic state (high or low logic level) andwhile high level the outputs will be in a high imped-ance state.It has same speed performance at 3.3V than 5VAC/ACT family, combined with a lower powerconsumption.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.
