Dual D-Type Flip Flop with Preset and Clear
The TC74AC74 is an advanced high speed CMOS D-FLIP
FLOP fabricated with silicon gate and double-layer metal wiring
C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The signal level applied to the D INPUT is transferred to Q
OUTPUT during the positive going transition of the CK pulse.
CLR and PR are independent of the CK and are
accomplished by setting the appropriate input to an “L” level.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: fmax = 200 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC (min)
Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 V to 5.5 V
Pin and function compatible with 74F74
Note: xxxFN (JEDEC SOP) is not available in
Japan.

Note:
CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC/2 (per F/F)
