INTEGRAL IN74LS05

TECHNICAL DATA
IN74LS05
Hex Inverters
with Open-Drain Outputs
This device contains idenpendent inverts. It performs the Boolean
function Y=A. The open collector outputs require pull-up resistor to
perform correctly. Open-collector devices are often used to generate
higher VOH levels.
