FEATURES  
DESCRIPTION  
The CBT3244 provides eight bits of high-speed TTL-compatible bus  
switching in a standard ’244 device pinout. The low on-state  
resistance of the switch allows connections to be made with minimal  
propagation delay.  
Functionally equivalent to QS3244  
Standard ’244-type pinout  
5switch connection between two ports  
TTL compatible control input levels  
The CBT3244 device is organized as two 4-bit low-impedance  
switches with separate output-enable (OE) inputs. When OE is low,  
the switch is on and data can flow from port A to port B, or vice  
versa. When OE is high, the switch is open and high-impedance  
state exists between the two ports.  
Package options include plastic small outline (D), shrink small  
outline (DB), thin shrink small outline (TSSOP)  
The CBT3244 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.

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

NOTES:  
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state  
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
