description
The ’AHC245 octal bus transceivers are designed
for
asynchronous
two-way
communication
between
data
buses.
The
control-function
implementation
minimizes
external
timing
requirements.
These devices allow data transmission 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
that 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 SN54AHC245 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74AHC245 is characterized for
operation from –40
°C to 85°C.
