74AHC1G79; 74AHCT1G79

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

The 74AHC1G79; 74AHCT1G79 is a single positive-edge triggered D-type flip-flop. Data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition will be stored in the flip-flop and appear at the Q output. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

Wide supply voltage range from 2.0 to 5.5 V
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
Symmetrical output impedance
Balanced propagation delays
Input levels:
- For 74AHC1G79: CMOS level
- For 74AHCT1G79: TTL level
ESD protection:
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Specified from -40 °C to +125 °C
