General
The 74HC393D is a high speed CMOS 4-BIT BINARY COUNTER fabricated with silicon gate C
2
MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power
dissipation.
It contains two independent counter circuits in one package, so that counting or frequency division of eight binary
bits can be achieved with one IC.
This device changes state on the negative going transition of the CK pulse. The counter can be reset to "0" (QA
to QD = "L") by a high at the CLR input regardless of other inputs.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
