description
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.
The SN54HC590A 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.
