It is ideal for 1.65 to 3.6 VCC operations and low power and low noise applications. These 8 bit D-Type latch are controlled by a latch enable input (LE) and an output enable input (OE). While the LE inputs is held at a high level, the Q SOP TSSOP ORDER CODES PACKAGE TUBE T&R SOP TSSOP 74LVC373AM 74LVC373AMTR 74LVC373ATTR outputs will follow the data input precisely or inversely. When the LE is taken low, the Q outputs will be latched precisely or inversely 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. This device is designed to interface directly High Speed CMOS systems with TTL and NMOS components. It has more speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
