TC74AC273FT

TC74AC273P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC273P, TC74AC273F, TC74AC273FT Octal D-Type Flip Flop with Clear The TC74AC273 is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Information signals applied to D inputs are transferred to the Q output on the positive going edge of the clock pulse. When the CLR input is held “L”, the Q outputs are at a low logic level independent of the other inputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: fmax = 170 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 8 μA (max) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min) Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 V to 5.5 V Pin and function compatible with 74F273 TC74AC273P TC74AC273F TC74AC273FT Weight DIP20-P-300-2.54A SOP20-P-300-1.27A TSSOP20-P-0044-0.65A : 1.30 g (typ.) : 0.22 g (typ.) : 0.08 g (typ.)
