74VHC393
Dual 4-Bit Binary Counter
General Description
The VHC393 is an advanced high speed CMOS 4-bit
Binary Counter fabricated with silicon gate CMOS technol-
ogy. It achieves the high speed operation similar to equiva-
lent Bipolar Schottky TTL while maintaining the CMOS low
power dissipation. It contains two independent counter cir-
cuits in one package, so that counting or frequency division
of 8 binary bits can be achieved with one IC. This device
changes state on the negative going transition of the
CLOCK pulse. The counter can be reset to “0” (Q0–Q3 =
“L”) by a HIGH at the CLEAR input regardless of other
inputs.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
s High Speed: fMAX = 170 MHz (typ) at TA = 25°C
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 Pin and function compatible with 74HC393
