TC74LCX573F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX573F TC74LCX573FK Low-Voltage Octal D-Type Latch with 5-V Tolerant Inputs and Outputs The TC74LCX573 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) VCC applications, but it could be used to interface to 5-V supply 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.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
