description/ordering information
The 'CBTD3384 devices provide ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switches allows connections to be made without adding propagation delay. A diode to VCC is integrated on the die to allow for level shifting from 5-V signals at the device inputs to 3.3-V signals at the device outputs. These devices are organized as two 5-bit switches with separate output-enable (OE) inputs. When OE is low, the switch is on, and port A is connected to port B. When OE is high, the switch is open, and the high-impedance state exists between the two ports.

Stresses beyond those listed under "absolute maximum ratings" 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. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7.

In applications with fast edge rates, multiple outputs switching, and operating at high frequencies, the output may have little or no level-shifting effect. NOTE 3: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.

VI = 2.4 V, II = 15 mA 35 35 50 Typical values are at VCC = 5 V, TA = 25°C. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. § Measured by the voltage drop between the A and 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.
