DESCRIPTION
The CBT16210 provides 20 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 is organized as a dual 10-bit bus switch with separate
output-enable (OE) inputs. It can be used as two 10-bit bus switches
or as one 20-bit bus switch. When OE is low, the associated 10-bit
bus switch is on, and port A is connected to port B. When OE is
high, the switch is open, and a high-impedance state exists between
the ports.
The CBT16210 is characterized for operation from 40
C to +85
C.

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 150
C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V

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.
