description
The
′BCT125A bus buffer features independent
line drivers with 3-state outputs. Each output is
disabled when the associated output-enable (OE)
input is high.
The SN54BCT125A is characterized for operation
over the full military temperature range of – 55
°C
to 125
°C. The SN74BCT125A is characterized for
operation from 0
°C to 70°C.
