853-2215 27501
FEATURES
5 switch connection between two ports
TTL compatible control input and output levels
Designed to be used in 5 V to 3.3 V level shifting applications
Latch-up protection exceeds 500 mA per JESD78
ESD protection exceeds 2000 V HBM per JESD22-A114, and
1000 V CDM per JESD22-C101
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.
