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)
• Ordering Information
