The low on-state resistance of the switch allows connections to be made with minimal propagation delay. 1A5 11 14 2A1 GND 12 13 2OE The CBT3384 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. SA00502 The CBT3384 is characterized for operation from –40 to +85 °C.

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.

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.
