The SN74ALS568A decade counter and ALS569A binary counters are programmable, count
up or down, and offer both synchronous and asynchronous clearing. All synchronous functions
are executed on the positive-going edge of the clock (CLK) input.
The clear function is initiated by applying a low level to either asynchronous clear (ACLR\) or
synchronous clear (SCLR\). Asynchronous (direct) clearing overrides all other functions of the
device, while synchronous clearing overrides only the other synchronous functions. Data is
loaded from the A, B, C, and D inputs by holding load (
) low during a positive-going
