DESCRIPTION
The CBTS3384 provides ten bits of high-speed TTL-compatible bus
switching. The low on-state resistance of the switch allows
connections to be made with minimal propagation delay.
The CBTS3384 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.
