FEATURES
PIN CONFIGURATION
• 5 Ω 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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:
1. All typical values are at VCC = 5 V, Tamb = 25 °C
2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is
determined by the lowest voltage of the two (A or B) terminals.

NOTE:
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
