TC74HC595AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC595AP,TC74HC595AF,TC74HC595AFN 8-Bit Shift Register/Latch (3-state) The TC74HC595A is a high speed 8-BIT SHIFT REGISTER/LATCH fabricated with silicon gate C2MOS technology. It achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC595A contains an 8-bit static shift register which feeds an 8-bit storage register. 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. And, since the parallel outputs are 3-state, it can be directly connected to 8-bit bus. This register can be used in serial-to-parallel conversion, data receivers, etc. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxFN (JEDEC SOP) is not available in Japan.

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). Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW. 4 2007-10-01 TC74HC595AP/AF/AFN Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 2 to 6 V Input voltage VIN 0 to VCC V VOUT 0 to VCC V −40 to 85 °C Output voltage Operating temperature Topr 0 to 1000 (VCC = 2.0 V) Input rise and fall time 0 to 500 (VCC = 4.5 V) tr, tf ns 0 to 400 (VCC = 6.0 V) Note: The operating ranges must be maintained to ensure the normal operation of the device.
