The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The CBT3245A device is organized as one 8-bit switch. When enable (OE) is LOW, the switch is on and port A is connected to port B. When OE is HIGH, the switch is open and a high-impedance state exists between the two ports. The CBT3245A is characterized for operation from -40 to +85 °C. A8 * THE DIE SUBSTRATE IS ATTACHED TO THIS PAD USING CONDUCTIVE DIE ATTACH MATERIAL. IT CANNOT BE USED AS A SUPPLY PIN OR INPUT. ** PIN 1 INDICATION DOT SA00649 Figure 2.

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.
