74VHC273FT  
CMOS Digital Integrated Circuits Silicon Monolithic  
74VHC273FT  
1. Functional Description  
Octal D-Type Flip-Flop with Clear  
2. General  
The 74VHC273 is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP 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.  
Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock  
pulse.  
When the CLR input is held "L", the Q outputs are at a low logic level independent of the other inputs.  
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.  
3. Features  
(1) High speed: fMAX = 165 MHz (typ.) at VCC = 5 V  
(2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25  
(3) High noise immunity: VNIH = VNIL = 28% VCC (min)  
(4) Power-down protection is provided on all inputs.  
(5) Balanced propagation delays: tPLH tPHL  
(6) Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V  
(7) Low noise: VOLP = 0.8 V (max)  
(8) Pin and function compatible with the 74 series  
(74AC/HC/AHC etc.) 273 type.  
4. Packaging
