counter’s outputs are stored in the output register at
the positive edge of the register clock (RCK). If the
register clear input (RCLR) is held ”L” the register is
cleared (synchronously to register clock for
HC692/HC693 and asynchronously for
HC690/HC691). All inputs are equipped with protec-
tion circuits against static discharge and transient
excess voltage.
