1 / 11 page  74ACT273 OCTAL D-TYPE FLIP FLOP WITH CLEAR PRELIMINARY DATA ® May 1999 s HIGH SPEED: fMAX = 190 MHz ns (TYP.) at VCC =5V s LOW POWER DISSIPATION: ICC =8 µA (MAX.) at TA =25 oC s COMPATIBLE WITH TTL OUTPUTS VIH =2V (MIN), VIL = 0.8V (MAX) s 50 Ω TRANSMISSION LINE DRIVING CAPABILITY s SYMMETRICAL OUTPUT IMPEDANCE: |IOH|=IOL = 24 mA (MIN) s BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL s OPERATING VOLTAGE RANGE: VCC (OPR) = 4.5V to 5.5V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 273 s IMPROVED LATCH-UP IMMUNITY DESCRIPTION The ACT273 is a high-speed CMOS OCTAL D-TYPE FLIP FLOP WITH CLEAR fabricated with sub-micron silicon gate and double-layer metal wiring C 2MOS technology. It is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Schottky TTL. Information signals applied to D inputs are transfered to the Q output on the positive going edge of the clock pulse. When the CLEAR input is held low, the Q outputs are held low independentely of the other inputs . 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.
