Product specification
10-bit bus switch with 5-bit output enables and Schottky undershoot protection
CBT3384
FEATURES
* 5 switch connection between two ports * TTL compatible control input and output levels * Undershoot protection included to prevent shoot through level
changes
DESCRIPTION
The CBT3384 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 CBT3384 device is organized as two 5-bit 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. The CBT3384 is characterized for operation from 0C to 85C.
* Latch-up protection exceeds 500 mA per JESD78 * ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101

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 150C. 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, TA = 25C 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.
