DESCRIPTION
The M74HC593 is an high speed CMOS 8-BIT
REGISTER COUNTER (3 STATE)
fabricated
with silicon gate C2MOS technology.
This device consists of a parallel input, 8 bit
storage register feeding an 8 bit binary counter.
Both the counter and register clocks are positive
edge triggered. In addition, the counter has direct
load and clear functions. Expansions is easily
accomplished by connecting RCO of first stage to
the count enable CCKEN, of the second stage etc.
The M74HC593 comes in a 20 pin package and
has 3 state I/O, which provides parallel counter
outputs.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
