Octal bus switch with output enable
Preliminary specification
CBT3245
FEATURES
Functionally equivalent to QS3245
Standard ’245-type pinout
5switch connection between two ports
TTL compatible control input levels
Package options include plastic small outline (D), shrink small
outline (DB), thin shrink small outline (TSSOP)
DESCRIPTION
The CBT3245 provides eight bits of high-speed TTL-compatible bus
switching in a standard ’245 device pinout. The low on-state
resistance of the switch allows connections to be made with minimal
propagation delay.
The CBT3245 device is organized as one 8-bit switch. When enable
(OE) is low, the 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 two ports.
The CBT3245 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.
