Clear function on the M74HC299 is asynchronous This device has four modes (HOLD, SHIFT LEFT, to CLOCK. SHIFT RIGHT and LOAD DATA). Each mode is All inputs are equipped with protection circuits chosen by two function select inputs (S0, S1). against static discharge and transient excess When one or both enable inputs, (G1, G2) are voltage.
