DUAL D-TYPE FLIP FLOP WITH PRESET AND CLEAR
s HIGH SPEED:
fMAX = 300 MHz (TYP.) at VCC = 5V
s LOW POWER DISSIPATION:
ICC = 4 µA (MAX.) at TA = 25 oC
s HIGH NOISE IMMUNITY:
VNIH = VNIL = 28% VCC (MIN.)

s SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 24 mA (MIN)
ORDER CODES :
74AC74B
74AC74M
s BALANCED PROPAGATION DELAYS:
A signal on the D INPUT is transferred to the Q
tPLH ≅ tPHL
OUTPUT during the positive going transition of
s OPERATING VOLTAGE RANGE:
the clock pulse.
VCC (OPR) = 2V to 6V
s PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 74
s IMPROVED LATCH-UP IMMUNITY
CLEAR and PRESET are independent of the
clock and accomplished by a low setting on the
appropriate input.
It is ideal for low power applications mantaining

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to
Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD • VCC • fIN + ICC/n (per circuit)
