description/ordering information
The SN74CBT16211A provides 24 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 device operates as a dual 12-bit bus switch or
single 24-bit bus switch. When 1OE is low, 1A is
connected to 1B. When 2OE is low, 2A is
connected to 2B.

†Stresses beyond those listed under β€œabsolute 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 β€œrecommended 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.

ΒΆMeasured 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.
