description/ordering informaton (continued)
These devices comprise two independent 4-bit binary counters, each having a clear (CLR) and a clock (CLK)
input. These devices change state on the negative-going transition of the CLK pulse. N-bit binary counters can
be implemented with each package, providing the capability of divide by 256. The
’
LV393A devices have parallel
outputs from each counter stage so that any submultiple of the input count frequency is available for system
timing signals.
These devices are fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the
outputs, preventing damaging current backflow through the devices when they are powered down.
