description
These quadruple bus buffer gates feature
independent line drivers with 3-state outputs.
Each output is disabled when the associated
output-enable (OE) input is low.
The SN54HC126 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74HC126 is characterized for
operation from –40
°
C to 85
°
C.
