M74HC273 Octal D-Type Flip-Flop with Clear

The M74HC273 is an high speed CMOS OCTAL D TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology.

Information signals applied to D inputs are transferred to the Q outputs on the positive-going edge of the clock pulse.

When the CLEAR input is held low, the Q output are in the low logic level independent of the other inputs.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.

技术特性

• HIGH SPEED :
  • fMAX = 66 MHz (TYP.) at VCC = 6V

• HIGH NOISE IMMUNITY:
  • VNIH = VNIL = 28 % VCC (MIN.)
• SYMMETRICAL OUTPUT IMPEDANCE:
  • |IOH| = IOL = 4mA (MIN)
• BALANCED PROPAGATION DELAYS:
  • tPLH tPHL
• WIDE OPERATING VOLTAGE RANGE:
  • VCC (OPR) = 2V to 6V
• PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 273
