It is ideal for low power, battery operated and low noise 3.3V applications. This 8 bit D-Type latch is controlled by a latch enable input (LE) and an output enable input (OE). While the LE input is held at a high level, the Q outputs will follow the data input 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 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. It combines high speed performance with the true CMOS low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 74LVX373 LOW VOLTAGE CMOS OCTAL D-TYPE LATCH (3-STATE NON INV.)
