Hi all,
I am currently completing a report comparing CMOS and TTL IC's. I am comparing a hex inverter IC, and need some assistance locating the output current (both high and low), of the CMOS hex inverter (CD74HC04).
I understand there is a max amount of current a device can sink or source whilst still maintaining a high or low logic level, so generally a max source/sink current is designated per output pin....
The datasheet is located here and I am comparing the CD74HC04 model (CMOS load only).
I can see the max rating state:
DC Output Source or Sink Current per Output Pin, IO
For VO > -0.5V or VO < VCC + 0.5V . = .±25mA
So as long as Vo is between than -0.5v and Vcc +0.5 the output pin is able to source and sink ±25mA per output?? So the high level output voltage for CMOS loads is 0.02A... meaning that the normal operating specs, output current is generally around 20mA per output pin?
Id appreciate a shove in the right direction
Thanks
