#189244 - ATF16V8BQL has Icc of ~1.5mA
Responding to: Koen De Ganck's previous message
Koen De Ganck said:

It is an old design and has changed ( processor and GAL ) during the years.
As the GAL draws a lot of current I changed this to lower or ('Z'ero) power.
Never had an issue until now.

The ATF16V8BQL has a typical measured Static Icc of ~1.5mA, so it is not as low as a 'Z' part, (which are uA-static region parts), but for many designs that run something else, 1.5mA is quite ok.
It is also a little cheaper than the ATF16V8CZ :)
