TC74VHC4040F/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC4040F,TC74VHC4040FT,TC74VHC4040FK 12-Stage Ripple Carry Binary Counter TC74VHC4040F The TC74VHC4040 is an advanced high speed CMOS 12-STAGE BINARY COUNTER/DIVIDER fabricated with silicon 2 gate C MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Setting CLR to high resets the counter to low. A negative transition on the CK input brings one increment into the counter. TC74VHC4040FT This counter provides all divided output stages, and at Q12, a 1/4096 divided frequency will be output. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Features TC74VHC4040FK High speed: f = 210 MHz (typ.) at V = 5 V max CC Low power dissipation: I = 4 A (max) at Ta = 25C CC High noise immunity: V = V = 28% V (min) NIH NIL CC Power down protection is provided on all inputs. Balanced propagation delays: t t pLH pHL Wide operating voltage range: V = 2 V to 5.5 V CC (opr) Low noise: V = 1.5 V (max) OLP Pin and function compatible with 74HC4040 Weight SOP16-P-300-1.27A : 0.18 g (typ.)
