Description
TC74VHC4020F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC4020F, TC74VHC4020FK 14-Stage Ripple Carry Binary Counter The TC74VHC4020 is an advanced high speed CMOS 14-STAGE BINARY COUNTER/DIVIDER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL whi
More View le 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 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.
