TC74VHC574F/FT/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

Octal D-Type Flip Flop with 3-State Output
The TC74VHC574 is advanced high speed CMOS OCTAL
FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate
C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This 8-bit D-type flip-flop is controlled by a clock input (CK)
and an output enable input ( OE ).
When the OE input is high, the eight outputs are in a high
impedance state.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
Features
• High speed: fmax = 180 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)
• Power down protection is provided on all inputs.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Low noise: VOLP = 1.2 V (max)
• Pin and function compatible with 74ALS574
