TC74AC377P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC377P,TC74AC377F Octal D-Type Flip-Flop TC74AC377P The TC74AC377 is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an enable input ( G ) The signal level applied to the D inputs are transferred to Q outputs during the positive going transition of CK. 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. 3 2007-10-01 TC74AC377P/F Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 2.0 to 5.5 V Input voltage VIN 0 to VCC V VOUT 0 to VCC V −40 to 85 °C Output voltage Operating temperature Topr Input rise and fall time Note: 0 to 100 (VCC = 3.3 ± 0.3 V) dt/dV ns/V 0 to 20 (VCC = 5 ± 0.5 V) The operating ranges must be maintained to ensure the normal operation of the device.
