74VHC540FT,74VHC541FT  
CMOS Digital Integrated Circuits Silicon Monolithic  
74VHC540FT,74VHC541FT  
1. Functional Description  
Octal Bus Buffer  
74VHC540FT: INVERTED, 3-STATE OUTPUTS  
74VHC541FT: NON-INVERTED, 3-STATE OUTPUTS  
2. General  
The 74VHC540FT/74VHC541FT are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon  
gate C2MOS technology.  
They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS  
low power dissipation.  
The 74VHC540FT is an inverting type, and the 74VHC541FT is a non-inverting type.  
When either G1 or G2 are high, the terminal outputs are in the 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  
3. Features  
(1) High speed: Propagation delay time = 3.7 ns (typ.) at VCC = 5 V  
(2) Low power dissipation: ICC = 4 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 V to 5.5 V  
(7) Low noise: VOLP = 1.0 V (max)  
(8) Pin and function compatible with 74 series (74AC/HC/AHC/LV etc.) 540 or 541 type.  
4. Packaging
