74VHC4040
12-Stage Binary Counter
Features
■ High speed; fMAX = 210MHz at VCC = 5V
■ Low power dissipation: ICC = 4A (Max.) at TA = 25°C
■ High noise immunity: VNIH = VNIL = 28% VCC (Min.)
■ Power down protection is provided on all inputs
■ Wide operating voltage range: VCC (Opr.) = 2V – 5.5V
■ Low noise: VOLP = 0.8V (Max.)
■ Pin and function compatible with 74HC4040
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 destruc-
tion due to mismatched supply and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number.
