74VHC21FT  
CMOS Digital Integrated Circuits Silicon Monolithic  
74VHC21FT  
1. Functional Description  
Dual 4-Input AND Gate  
2. General  
The 74VHC21FT is an advanced high speed CMOS 4-INPUT AND GATE 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.  
The internal circuit is composed of 4 stages including a buffer output, which provide high noise immunity and  
stable output.  
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) AEC-Q100 (Rev. H) (Note 1)  
(2) Wide operating temperature: Topr = -40 to 125  
(3) High speed: tpd = 3.3 ns (typ.) at VCC = 5.0 V  
(4) Low power dissipation: ICC = 2.0 µA (max) at Ta = 25   
(5) High noise immunity: VNIH = VNIL = 28 % VCC (min)  
(6) Power down protection is provided on all inputs.  
(7) Balanced propagation delays: tPLH tPHL  
(8) Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V  
(9) Pin and function compatible with the 74 series (AC/HC/AHC/LV etc.) 21 type.  
Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales  
representative.
