DESCRIPTION
The 74ACT299 is an advanced high-speed CMOS 8-BIT PIPO SHIFT REGISTER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

■ HIGH SPEED: fMAX = 240MHz (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION: ICC = 8µA(MAX.) at TA=25°C
■ COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.), VIL = 0.8V (MAX.)
■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGE RANGE: VCC (OPR) = 4.5V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 299
■ IMPROVED LATCH-UP IMMUNITY
