Product Summary
The SN74AHC74DR is a dual positive-edge-triggered D-type FLIP-FLOP. A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs, regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse.
Parametrics
SN74AHC74DR absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 7 V; (2)Input clamp current:-20 mA; (3)Output clamp current: ±20 mA; (4)Continuous output current: ±25 mA; (5)Continuous current through VCC or GND: +/-50 mA; (6)Package thermal impedance: 86°C/W; (7)Storage temperature range: -65°C to 150°C.
Features
SN74AHC74DR features: (1)operating range 2-V to 5.5-V Vcc; (2)latch-up performance exceeds 250 mA perJESD 17; (3)ESD Protection Exceeds JESD 22: 2000-V Human-Body Model (A114-A), 200-V Machine Model (A115-A, 1000-V Charged-Device Model (C101).
