1 / 8 page TC74HC273AP/AF 2007-10-01 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC273AP,TC74HC273AF Octal D-Type Flip Flop with Clear The TC74HC273A is a high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Information signals applied to D inputs are transferred to the Q outputs 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 = 67 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Wide operating voltage range: VCC (opr) = 2~6 V • Pin and function compatible with 74LS273 Pin Assignment TC74HC273AP TC74HC273AF Weight DIP20-P-300-2.54A : 1.30 g (typ.) SOP20-P-300-1.27A : 0.22 g (typ.) |
