DESCRIPTIONThe 74VHCT16373A is an advanced high-speedCMOS 16 BIT D-TYPE LATCH with 3 STATEOUTPUTS NON INVERTING fabricated withsub-micron silicon gate and double-layer metalwiring C2MOS technology.These 16 bit D-TYPE latches are byte controlledby two latch enable inputs (nLE) and two outputenable inputs(nOE).While the nLE input is held at a high level, the nQoutputs will follow the data (D) inputs.When the nLE is taken LOW, the nQ outputs willbe latched at the logic level of D data inputs.When the (nOE) input is low, the nQ outputs willbe in a normal logic state (high or low logic level);when nOE is at high level ,the outputs will be in ahigh impedance state.Power down protection is provided on all inputsand 0 to 7V can be accepted on inputs with noregard to the supply voltage. This device can beused to interface 5V to 3V.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.
