description
The ’CBTD3384 devices 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.
