Functional DescriptionFunctional DescriptionFunctional DescriptionFunctional Description Low-Voltage Octal D-Type Latch with 5-V Tolerant Inputs and Outputs 2. 2. GeneralGeneral 2. 2. GeneralGeneral The 74LCX573FT is a high-performance CMOS octal D-type latch. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) V applications, but it could be used to interface to 5-V supply CC environment for both inputs and outputs. This 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE). When the OE input is high, the eight outputs are in a high-impedance state. All inputs are equipped with protection circuits against static discharge. 3. 3. 3. 3.
