| TC7MH4040FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MH4040FK 12-Stage Ripple-Carry Binary Counter The TC7MH4040FK is an advanced high speed CMOS 12-stage ripple-carry binary counter fabricated with silicon gate C2MOS 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. This counter provides all divided output stages, and at Q12, a Weight: 0.02 g (typ.) 1/4096 divided frequency will be output. An input protection circuit ensures that 0 to 7 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 * * * * * * * * High speed: fmax = 210 MHz (typ.) (VCC = 5 V) Low power dissipation: ICC = 4 A (max) (Ta = 25C) High noise immunity: VNIH = VNIL = 28% VCC (min) Power down protection is provided on all inputs. Balanced propagation delays: tpLH tpHL - Wide operating voltage range: VCC (opr) = 2~5.5 V Low noise: VOLP = 1.5 V (max) Pin and function compatible with 74HC4040 000630EBA1 * TOSHIBA is continually working to improve the quality and reliability of its products.
