TOSHIBA TC74HC273AF(EL,F)

The TC74HC273A is a high-speed CMOS octal D-type flip-flop fabricated using silicon gate C²MOS technology. It achieves high-speed operation comparable to equivalent LSTTL while maintaining the low power consumption characteristic of CMOS. The information signal applied to the D input is transferred to the Q output on the rising edge of the clock pulse. When the CLR (overline) input is held "L", the Q output is at a low logic level, regardless of other inputs. All inputs are equipped with protection circuits against electrostatic discharge or transient overvoltage.

• High-speed: fmax = 67 MHz (typ.) at VCC = 5 V
• Low power consumption: ICC = 4 μA (max.) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min.)
• Output drive capability: 10 LSTTL loads
• Symmetric output impedance: |IOH| = IOL = 4 mA (min.)
• Balanced propagation delay: tₚLH ≃ tₚHL
• Wide operating voltage range: VCC (operating) = 2 ~ 6 V
• Pin and function compatible with 74LS273
