FEATURES 5 Ω switch connection between two ports TTL compatible control input levels Latch-up testing is done to JEDEC Standard JESD78 which
exceeds 100 mA ESD protection exceeds 1500 V HBM per JESD22-A114 and
1000 V CDM per JESD22-C101
DESCRIPTIONThe 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 +85°C.

ABSOLUTE MAXIMUM RATINGS1, 2
NOTES: 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. 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. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
RECOMMENDED OPERATING CONDITIONS
DC ELECTRICAL CHARACTERISTICS
NOTES: All typical values are at VCC = 5 V, Tamb = 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 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.

AC CHARACTERISTICSGND = 0 V; tR; CL = 50 pF
NOTES: This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
