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
