DESCRIPTION 74ACT299 advanced high-speed CMOS 8-BIT PIPO SHIFT REGISTER (3-STATE) fabricated with sub-micron silicon gate double-layer metal wiring C2MOS technology. These devices have four modes (HOLD, SHIFT LEFT, SHIFT RIGHT LOAD DATA). Each mode chosen function select inputs (S0, shown Truth Table. When CONNECTION LOGIC SYMBOLS
both enable inputs, (G1, high, eight input/output terminals high-impedance state; however sequential operation clearing register affected. Clear function asynchronousto clock. device designed interface directly High Speed CMOS systems with TTL, NMOS CMOS output voltage levels. inputs outputs equipped with protection circuits against static discharge, giving them immunity transient excess voltage.
