TC7W74FK,LF Toshiba

TC7W74FU/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7W74FU, TC7W74FK D-Type Flip Flop with Preset and Clear 2 The TC7W74 is a high speed C MOS D Flip Flop fabricated TC7W74FU 2 with silicon gate C MOS technology. It achieves the high speed operation similar to equivalent 2 LSTTL while maintaining the C MOS low power dissipation. The signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CLOCK pulse CLEAR and PRESET are independent of the CLOCK and are accomplished by setting the appropriate input to an L level Input is equipped with protection circuits against static discharge or transient excess voltage. (SM8) TC7W74FK Features High speed: f = 77 MHz (typ.) at V = 5 V MAX CC Low power dissipation: I = 2 A (max) at Ta = 25C CC High noise immunity: V = V = 28% V (min) NIH NIL CC Output drive capability: 10 LSTTL loads Symmetrical output impedance: I = I = 4 mA (min) OH OL Balanced propagation delays: t t pLH pHL Wide operating voltage range: V (opr) = 2 to 6 V CC (US8) Weight Marking SSOP8-P-0.65: 0.02 g (typ.)

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).
