24-bit bus exchange switch with 12-bit output enables
CBT16212
FEATURES
* 5 switch connection between two ports * TTL compatible control input levels * Latch-up testing is done to JEDEC Standard JESD78 which
exceeds 100 mA
DESCRIPTION
The CBT16212 provides 24 bits of high-speed TTL-compatible bus switching or exchanging. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The CBT16212 operates as 24-bit bus switch or a 12-bit bus exchanger, which provides data exchanging between the four signal ports via the data-select (S0-S2) terminals. The CBT16212 is characterized for operation from -40 to +85C.
* ESD protection exceeds 1500 V HBM per JESD22-A114 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, 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.
