TC74VHC9595FK(EL,K

TC74VHC9595FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC9595FK 8-Bit Shift Register/Latch The TC74VHC9595 is an advanced high speed 8-BIT SHIFT REGISTER/LATCH fabricated with silicon gate C2MOS technology. TC74VHC9595 combines low power consumption of CMOS with Schottky TTL speeds. Shift operation is accomplished on the positive going transition of the SCK input. The output register is loaded with the contents of the shift register on the positive going transition of the RCK input. Since RCK and SCK signal are independent, parallel outputs can be held stable during the shift operation. This register can be used in serial-to-parallel conversion, data receivers, etc. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the TC74VHC9595 is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Additionally, all the inputs have a newly developed protection circuit without a diode returned to VCC. This enables the inputs to be tolerant of up to 5.5 volts even when power supply is down. The input power-down protection capability makes the TC74VHC9595 ideal for a wide range of applications, such as interfacing between different voltages, voltage translation from 5 V to 3 V and battery back-up circuits. A variant of the TC 74HC/VHC/AHC/LV595, the TC74VHC9595 contains negative-edge-triggered flip-flops to improve timing margins that are affected by long wires or slowly changing clocks when multiple parts are cascaded together.

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).
