HD74HCT125, HD74HCT126  
Quad. Bus Buffer Gates (with 3-state outputs)  
REJ03D0657–0200  
(Previous ADE-205-545)  
Rev.2.00  
Mar 30, 2006  
Description  
The HD74HCT125, HD74HCT126 require the 3-state control input C to be taken high to put the output into the high  
impedance condition, whereas the HD74HCT125, HD74HCT126 requires the control input to be low to put the output  
into high impedance.  
Features  
LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility  
High Speed Operation: tpd (A to Y) = 12 ns typ (CL = 50 pF)  
High Output Current: Fanout of 15 LSTTL Loads  
Wide Operating Voltage: VCC = 4.5 to 5.5 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
