74VHC393
Dual 4-Bit Binary Counter
Features
■ High Speed: fMAX = 170MHz (Typ.) at TA = 25°C
■ 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
■ Pin and function compatible with 74HC393
General Description
The VHC393 is an advanced high speed CMOS 4-bit
Binary Counter fabricated with silicon gate CMOS tech-
nology. It achieves the high speed operation similar to
equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation. It contains two indepen-
dent counter circuits 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
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery back
up. This circuit prevents device destruction due to mis-
matched supply and input voltages.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
All packages are lead free per JEDEC: J-STD-020B standard.
