74VHC4020FT(BJ)

74VHC4020FT(BJ) is a CMOS digital silicon monolithic IC. It 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 while maintaining the CMOS low power dissipation. Setting CLR to high resets the counter to low. A negative transition on the active-low 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 5.5V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back-up. This circuit prevents device destruction due to mismatched supply and input voltages.
