TC74VCXH16373FT

TC74VCXH16373FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXH16373FT Low-Voltage 16-Bit D-Type Latch with Bushold The TC74VCXH16373FT is a high-performance CMOS 16-bit D-type latch. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This 16-bit D-type latch is controlled by a latch enable input (LE) and an output enable input ( OE ) which are common to each byte. It can be used as two 8-bit latches or one 16-bit latch. When the OE input is high, the outputs are in a high-impedance state. The D data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. All inputs are equipped with protection circuits against static discharge. Weight: 0.25g (typ.)

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).
