description
These octal bus transceivers are designed for 2-V
to 5.5-V VCC operation.
The
’LV245A
devices
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
on
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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54LV245A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LV245A is characterized for operation from –40
°C to 85°C.
