Overview
TC74VHC574F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC574F, TC74VHC574FK 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 A (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.
0 V (max)  Pin and function compatible with 74ALS574 TC74VHC574F TC74VHC574FK Weight SOP20-P-300-1.
