TC74VCX373FK

TC74VCX373FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX373FT, TC74VCX373FK Low-Voltage Octal D-Type Latch with 3.6 V Tolerant Inputs and Outputs The TC74VCX373 is a high performance CMOS octal D-type latch which is guaranteed to operate from 1.2-V to 3.6-V. Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. The 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).
