TC74AC74P
1. Functional Description
• Dual D-Type Flip-Flop with Preset and Clear
2. General
The TC74AC74P 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.
3. Features
(1) High speed: fMAX = 200 MHz (typ.) at VCC = 5.0 V
(2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25
(3) High noise immunity: VNIH = VNIL = 28% VCC (min)
(4) Output current: |IOH|/IOL = 24 mA (min) (VCC = 4.5 V)
(5) Balanced propagation delays: tPLH ≈ tPHL
(6) Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V
(7) Pin and function compatible with 74F74.
