74VHCT125AFT,74VHCT126AFT  
CMOS Digital Integrated Circuits Silicon Monolithic  
74VHCT125AFT,74VHCT126AFT  
1. Functional Description  
Quad Bus Buffer, Non-Inverted 3-State Outputs  
74VHCT125AFT:QUAD BUS BUFFER  
74VHCT126AFT:QUAD BUS BUFFER  
2. General  
The 74VHCT125A and 74VHCT126A are high speed CMOS QUAD BUS BUFFERs fabricated with silicon gate  
C2MOS technology.  
They achieve the high speed operation similar to equivalent Bipolar Shottky TTL while maintaining the CMOS  
low power dissipation.  
The 74VHCT125A requires the 3-state control input G to be set high to place the output into the high impedance  
state, whereas the 74VHCT126A requires the control input G to be set low to place the output into high impedance.  
The input voltage are compatible with TTL output voltage.  
This device may be used as a level converter for interfacing 3.3 V to 5 V system.  
Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without  
regard to the supply voltage. There structure prevents device detsruction due to mismatched supply and input/  
output voltages such as battery back up, hot board insertion, etc.  
Note: Output in off-state  
3. Features  
(1) High speed: Propagation delay time = 3.8 ns (typ.) at VCC = 5 V  
(2) Quiescent supply current: ICC = 4 µA (max) at Ta = 25  
(3) Compatible with TTL input: VIL = 0.8 V(max)  
VIH = 2.0 V(min)  
(4) Power down protection is provided on all inputs and outputs.  
(5) Balanced propagation delays: tPLH tPHL  
(6) Low noise: VOLP = 0.8 V (max)  
(7) Pin and function compatible with the 74 series  
(74ACT/HCT/AHCT etc.) 125/126 type.
