74VHC4040 12-Stage Binary Counter August 1993 Revised April 1999 74VHC4040 12-Stage Binary Counter General Description The VHC4040 is an advanced high-speed CMOS device fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC4040 is a 12-stage counter which increments on the negative edge of the input clock and all outputs are reset to a low level by applying a logical high on the reset input. An input protection circuit insures that 0V to 7V can be applied to the inputs without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup.
