HD74HCT126 Datasheet Quad. Bus Buffer Gates (with 3-state Outputs)

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HCT125/HD74HCT126 Quad. Bus Buffer Gates (with 3-state outputs).

General 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.

Key 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) Function Table Input C HCT125 H L L HCT126 L H H A X L H Output Y HD74HCT125 Z L H HD74HCT126 Z L H Notes: X: Irrelevan.
