74AHC(T)1G79

Single D-type flip-flop; positive-edge trigger

74AHC1G79 and 74AHCT1G79 are high-speed Si-gate CMOS devices. They provide a single positive-edge triggered D-type flip-flop.

Information on the data input is transferred to the Q output on the LOW-to-HIGH transition of the clock pulse. The D input must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.

The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.

The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.

Features

  • Symmetrical output impedance
  • High noise immunity
  • Low power dissipation
  • Balanced propagation delays
  • SOT353-1 and SOT753 package options
  • ESD protection:
    • HBM JESD22-A114F: exceeds 2000 V
    • MM JESD22-A115-A: exceeds 200 V
    • CDM JESD22-C101C: exceeds 1000 V
  • Specified from -40 °C to +125 °C
