description
These octal bus transceivers are designed for
2.7-V to 5.5-V V
CC
operation.
The ’LV245 are designed for asynchronous
communication between data buses. The device
transmits data from the A bus to the B bus or from
the B bus to the A bus, depending upon the logic
level at the direction-control (DIR) input. The
output-enable (OE) input can be used to disable
the device so the buses are effectively isolated.
The SN74LV245 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54LV245 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74LV245 is characterized for operation from –40
°
C to 85
