CBTD16211
DESCRIPTION
The CBTD16211 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.
A diode to V
between 5 V inputs and 3.3 V outputs.
The device is organized as a dual 12-bit bus switch with separate
output-enable (OE
or as one 20-bit bus switch. When OE
bus switch is on, and port A is connected to port B. When OE
high, the switch is open, and a high-impedance state exists between
the ports.
The CBTD16211 is characterized for operation from –40 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 ju nction
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.
