description
The ’CBTD3384 provide ten bits of high-speed
TTL-compatible bus switching. The low on-state
resistance of the switches allows connections to
be made without adding propagation delay. A
diode to V
CC
is integrated on the die to allow for
level shifting between 5-V inputs and 3.3-V
outputs.
These devices are organized as two 5-bit
switches with separate output-enable (OE
)
inputs. When OE
is low, the switch is on and port
A is connected to port B. When OE
is high, the
switch is open and a high-impedance state exists
between the two ports.
The SN54CBTD3384 is characterized for
operation over the full military temperature range
from –55°C to 125°C. The SN74CBTD3384 is
characterized for operation from –40°C to 85°C.
