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. This circuit prevents device destruction due to mismatched supply and input voltages.
Features
s High speed; fMAX = 210 MHz at VCC = 5V s Low power dissipation: ICC = 4 µA (max) at TA = 25°C s High noise immunity: VNIH =VNIL = 28% VCC (min) s Power down protection is provided on all inputs s Wide operating voltage range: VCC (opr) = 2V - 5.5V s Low noise: VOLP = 0.8V (max) s Pin and function compatible with 74HC4040

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

Note 3: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPD * VCC * fN + ICC.
