8-BIT BINARY COUNTERS
WITH 3-STATE OUTPUT
REGISTERS

DESCRIPTION
The UTC 74HC590 contains an 8-bit binary counter that feeds
an 8-bit storage register and 3-state outputs.. The storage register
has parallel (QA~QH) outputs.
SOP-16
The binary counter features direct clear ( CCLR ) and
count-enable ( CCKEN ) inputs. A ripple-carry output ( RCO ) is
provided for cascading. Expansion is accomplished easily for two
stages by connecting ( RCO ) of the first stage to CCKEN of the
second stage. Cascading for larger count chains can be
accomplished by connecting( RCO )of each stage to the counter
clock (CCLK) input of the following stage.

FEATURES
* Wide supply voltage range from 2.0V to 6.0V
* Low static power consumption; ICC=8μA (Max.)
* 8 bit counter with register
