74AC74U
Lot size: 4
Case: SOIC-14
Advanced CMOS family Dual D Flip-Flop with Preset + Reset, 125MHz BW
Genuine components from USA; No China parts!
CMOS "AC" series LOGIC
AC logic family has:
3 x Faster propagation delay than "HC/HCT", 10-20 faster than "CD4000"
4 x the bandwidth of "HC", 40 x that of "CD4000", highest BW of any conventional logic family
24mA output drive current sink/source, 3x better than "HC", 10 x better than "4000"
The AC74 devices are dual positive-edge-triggered D-type flip-flops.
A low level at the preset (PRE)\ or clear (CLR)\ input 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. 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 D can be changed without affecting the levels at the outputs.
