These devices have four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and LOAD DATA). Each mode is chosen by two function select inputs (S0, DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP 74AC299B 74AC299M T&R 74AC299MTR 74AC299TTR S1) as shown in the Truth Table. When one or both enable inputs, (G1, G2) are high, the eight input/output terminals are in the high-impedance state; however sequential operation or clearing of the register is not affected. Clear function is asynchronous to clock. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
