It is ideal for low power, batteryoperated and low noise 3.3V applications.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.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 be used to interface 5V to 3V. Itcombines high speed performance with the trueCMOS low power consumption.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.February 2003 1/10 74LVX16373 INPUT EQUIVALENT CIRCUIT PIN DESCRIPTION IEC LOGIC SYMBOLS PIN No SYMBOL NAME AND FUNCTION 1 1OE 3 State Output EnableInput (Active LOW) 2, 3, 5, 6, 8, 9, 1Q0 to 1Q7 3-State Outputs 11, 12 13, 14, 16, 17, 2Q0 to 2Q7 3-State Outputs 19, 20, 22, 23 24
