DESCRIPTION
The M54/74HC592 is a high speed CMOS 8 BIT
REGISTER COUNTER fabricated in silicon gate
C²MOS technology. It has the same high speed per-
formance of LSTTL combined with true CMOS low
power consumption.
The M54/74HC592 is a parallel input, 8 bit storage
register feeding an 8 bit binary counter. Both the reg-
ister and the counter have individual positive edge
triggered clock. In addition, the counter has direct
load and clear functions. Expansion is easily accom-
plished by connecting RCO af the first stage to the
count enable of the second stage. All inputs are
equipped with protection circuits against static dis-
charge and transient excess voltage.
