FEATURES
DESCRIPTION
The CBTD3384 provides ten bits of high-speed TTL-compatible
level shifting bus switching. The low on-state resistance of the
switch allows connections to be made with minimal propagation
delay. The gate voltage of the enabled switch is lowered by a diode
to allow convenient level shifting between 5 V and 3.3 V levels on
either side of the CBTD3384.
The CBTD3384 device is organized as two 5-bit bus switches with
separate output-enable (OE) inputs. When OE is low, the switch is
on and port A is connected to B. When OE is high, the switch is
open and high-impedance state exists between the two ports.
The CBTD3384 is characterized for operation from –40 to +85 C.
