The ’CBT3383 devices provide ten 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 devices operate as a 10-bit bus switch or a 5-bit bus exchanger, which provides swapping of the A and B
pairs of signals. The bus-exchange function is selected when BX is high. The switches are connected when BE
is low.
The SN54CBT3383 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74CBT3383 is characterized for operation from 0°C to 70°C.

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.

A
CC
This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
or GND.
CC
Measured by the voltage drop between the input terminal and the output terminal at the indicated current through the switch. On-state resistance
is determined by the lowest voltage of the two (A or B) terminals.
