Overview: ® 74ACT299 8 BIT PIPO SHIFT REGISTER WITH ASYNCHRONOUS CLEAR PRELIMINARY DATA s s s s s s s s s HIGH SPEED: fMAX = 170 MHz (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 8 µA (MAX.) at TA = 25 oC PATIBLE WITH TTL OUTPUTS VIH = 2V (MIN), VIL = 0.8V (MAX) 50Ω TRANSMISSION LINE DRIVING CAPABILITY SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 4.5V to 5.5V PIN AND FUNCTION PATIBLE WITH 74 SERIES 299 IMPROVED LATCH-UP IMMUNITY B M (Plastic Package) (Micro Package) ORDER CODES : 74ACT299B 74ACT299M These devices have four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and LOAD DATA). Each mode is chosen by two function select inputs (S0, 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 synchronous to clock. The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
