SN54AHC74F

The SN54AHC74F dual positive-edge-triggered devices are D-type flip-flops.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 of SN54AHC74F at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval,data at the D input can be changed without affecting the levels at the outputs.

Features of the SN54AHC74F are:(1)Operating Range 2-V to 5.5-V VCC; (2) Latch-Up Performance Exceeds 250 mA Per JESD 17; (3)SD Protection Exceeds JESD 22  2000-V Human-Body Model (A114-A)  200-V Machine Model (A115-A)  1000-V Charged-Device Model (C101).

The absolute maximum ratings of the SN54AHC74F can be summarized as:(1)Supply voltage range, VCC:-0.5 V to 7 V; (2)Input voltage range, VI: -0.5 V to 7 V; (3)Output voltage range, VO:-0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI0): -20 mA ; (5)Output clamp current, IOK (VO < 0 or VO > VCC):  ±20 mA; (6)Continuous output current, IO (VO = 0 to VCC):±25 mA; (7)Continuous current through VCC or GND:±50 mA; (8)Storage temperature range, Tstg :-65°C to 150°C.
