TC74AC374P/F/FT,534P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC374P,TC74AC374F,TC74AC374FT TC74AC534P,TC74AC534F Octal D-Type Flip-Flop with 3-state Output TC74AC374P/F/FT Non-Inverting TC74AC534P/F Inverting TC74AC374P, TC74AC534P The TC74AC374 and TC74AC534 are advanced high speed CMOS OCTAL FLIP-FLOPS fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. These 8-bit D-type flip-flops are controlled by a clock input (CK) and a output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state. The TC74AC374 has non-inverting outputs, and TC74AC534 has inverting outputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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 should be applied up to 300 mW.
