description  
GND  
The ’HC590A contain an 8-bit binary counter that  
feeds an 8-bit storage register. The storage  
register has parallel outputs. Separate clocks are  
provided for both the binary counter and storage  
register. The binary counter features direct clear  
(CCLR) and count-enable (CCKEN) inputs. A  
ripple-carry output (RCO) is provided for  
cascading. Expansion is easily accomplished 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.

Both CCLK and the register clock (RCLK) input  
are positive-edge triggered. If both clocks are  
connected together, the counter state is always  
one count ahead of the register. Internal circuitry  
prevents clocking from the clock enable.  
NC – No internal connection  
TheSN54HC590A is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74HC590A is characterized for operation from –40°C to 85°C.
