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 dissi-
pation. The VHC4040 is a 12-stage counter which incre-
ments 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. This circuit prevents device destruction due to mis-
matched supply and input voltages.

Note 1:
Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside databook specifica-
tions.
Note 2:
Unused inputs must be held HIGH or LOW. They may not float
