description
These bus buffer gates feature independent line
drivers with 3-state outputs. Each output is
disasbled when the associated output-enable
(OE) input is high.
The SN54HCT125 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74HCT125 is characterized for
operation from –40
°
C to 85
°
