SN54HCT74, SN74HCT74 DUAL DĆTYPE POSITIVEĆEDGEĆTRIGGERED FLIPĆFLOPS WITH CLEAR AND PRESET SCLS169E - DECEMBER 1982 - REVISED APRIL 2004 D Operating Voltage Range of 4.5 V to 5.5 V D Outputs Can Drive Up To 10 LSTTL Loads D Low Power Consumption, 40-µA Max ICC D Typical tpd = 17 ns D ±4-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Inputs Are TTL-Voltage patible description/ordering information The ’HCT74 devices contain two independent D-type positive-edge-triggered 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 at the data (D) input meeting...
