The M74HC273 is a 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.
The M74HC273 is a high-speed CMOS octal D-type flip-flop with clear, fabricated with silicon gate C2MOS technology. Data applied to the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse; when CLEAR is held low, the Q outputs are at the low logic level independent of the other inputs. All inputs have protection circuits against static discharge and transient excess voltage, and the device is pin and function compatible with 74 series 273.
This datasheet provides the pin connection and IEC logic symbols, pin description, truth table and logic diagram, followed by absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, test circuit and waveforms. It also gives mechanical data for the Plastic DIP-20, SO-20 and TSSOP20 packages and lists the available order codes.
