Description:
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 to 6 V
• Pin and function compatible with 74LS273
