产品概述
The 'LS592 comes in a 16-pin package and consists of a parallel input,
8-bit storage register feeding an 8-bit binary counter. Both the register
and the counter have individual positive-edge-triggered clocks. In addition,
the counter has direct load and clear functions. A low-going RCO pulse will be obtained when the counter reaches the hex word FF. 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 CCK of the following stage.
The 'LS593 comes in a 20-pin package and has all the features of the 'LS592
plus 3-state I/O, which provides parallel counter outputs. The tables below
show the operation of the enable (CCKEN, CCKEN\) inputs. A register
clock enable (RCKEN\) is also provided.
