Octal D-Type Flip-Flop with 3-State Output
The TC74AC574 is an advanced high speed CMOS OCTAL
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.
These 8-bit D-type flip-flops are controlled by a clock input
(CK) and a output enable input ( OE ).
When the OE input is high, the eight outputs are in a high
impedance state.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: fmax = 180 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 8 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
transmission lines
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 to 5.5 V
Pin and function compatible with 74F574
Note: xxxFW (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/8 (per F/F)
And the total CPD when n pcs. of latch operate can be gained by the following equation:
CPD (total) = 26 + 10·n
