description
The ’HC266 are composed of four independent
2-input
exclusive-NOR
gates
and
feature
open-drain outputs. They perform the Boolean
function Y = A
B or Y = AB + AB in positive logic.
The SN54HC266 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74HC266 is characterized for
operation from –40
°C to 85°C.
