Counter Single 12-Bit Binary UP 16-Pin SOIC N T/R

The 74VHC4040 is a 12-Stage Binary Counter The VHC4040 is an advanced high-speed CMOS devicefabricated with silicon gate CMOS technology. Itachieves the high-speed operation similar to equivalentBipolar Schottky TTL while maintaining the CMOS lowpower dissipation. The VHC4040 is a 12-stage counterwhich increments on the negative edge of the input clockand all outputs are reset to a low level by applying alogical high on the reset input. An input protection circuitinsures that 0V to 7V can be applied to the inputs withoutregard to the supply voltage. This device can be used tointerface 5V to 3V systems and two supply systems suchas battery backup. This circuit prevents device destruc-tion due to mismatched supply and input voltages
