MC74ACT05
Hex Inverter With
OpenĆDrain Outputs
HEX INVERTER WITH
OPEN-DRAIN OUTPUTS
The MC74AC/ACT05 is identical in pinout to the LS05. The device inputs are
compatible with standard CMOS outputs; with pullup resistors, they are compatible
with TTL outputs.
• Outputs Source/Sink 24 mA
• ′ACT05 Has TTL Compatible Inputs
